Re: [R] Degree symbol as axis label superscript

[Bert Gunter]

Yes, but I should acknowledge my ignorance in not realizing that "\u00b0"
(hex 176) is a simpler way to get the character in R without the OS tool
than intToUtf8() .  If you need math notation beyond simple symbol
characters, plotmath is certainly indispensable.

Re: [R] Degree symbol as axis label superscript

[Andrew Simmons]

Using the degree character seems perfectly legit to me. The reason I
suggest looking at plotmath is that I think plotmath is easier to read
(that is, if you're escaping your characters with \u), and because for
anything more complicated like set notation, big sums, integrals, you'll
need to get used to plotmath to make your labels. Either way, nice
suggestion, both work perfectly well for this situation

Re: [R] Question about Rfast colMins and colMaxs

[Avi Gross via R-help]

Stephen,

Although what is in the STANDARD R distribution can vary several ways, in
general, if you need to add a line like:

library(something)
or
require(something)

and your code does not work unless you have done that, then you can imagine
it is not sort of built in to R as it starts.

Having said that, tons of exceptions may exist that cause R to load in
things on your machine for everyone or just for you without you having to
notice.

I think this forum lately has been deluged with questions about all kinds of
add-on packages and in particular, lots of the ones in the tidyverse.
Clearly the purpose here is not that broad.

But since I use some packages like the tidyverse extensively, and I am far
from alone, I wonder if someday the powers that be realize it is a losing
battle to exclude at least some of it. It would be so nice not having to
include a long list of packages for some programs or somehow arrange that
people using something you shared had installed and loaded them. But there
are too many packages out there of varying quality and usefulness and
popularity with more every day being added. Worse, many are somewhat
incompatible such as having functions with the same names that hide earlier
ones loaded.

Base R doe come with functions like colSums and colMeans and similar row
functions. But as mentioned, a data.frame is a list of vectors and R
supports certain functional programming constructs over lists using things
like:

lapply(df, min)
sapply(df, min)

And actually quite a few ways depending on what info you want back and
whether you insist it be returned as a list or vector or other things . You
can even supply additional arguments that might be needed such as if you
want to ignore any NA values,

lapply(df, min, na.rm=TRUE

The package you looked at it is trying to be fast and uses what looks like
compiled external code but so does lapply.

If this is too bothersome for you, consider making a one-liner function like
this:

mycolMins <- function(df, ...) lapply(df, min, ...)

Once defined, you can use that just fine and not think about it again and I
note this answer (like others) is offering you something in base R that
works fine on data.frames and the like.

You can extend to many similar ideas like this one that calulates the min
unless you over-ride it with max or mean or sd or a bizarre function like
`[` so a call to:

mycolCalc(df, `[`, 3)

Will return exactly the third items in each row!

I find it to be very common for someone these days to do a quick search for
a way to do something in a language like R and not really look to see if it
is a standard way or something special/ Matrices in R are not quite the same
as some other objects like a data.frame or tibble and a package written to
be used on one may (or may not) happen to work with another. Some packages
are carefully written to try to detect what kind of object it gets and when
possible convert it to another. The "apply" function is meant for matrices
but if it sees something else it looks ta the dimensionality and tries to
coerce it with as.matrix or as.array first. As others have noted, this mean
a data.frame containing non-numeric parts may fail or should have any other
columns hidden/removed as in this df that has some non-numeric fields:

> df
i   s   f b i2
1 1   hello 1.2  TRUE  5
2 2   there 2.3 FALSE  4
3 3 goodbye 3.4  TRUE  3

So a bit more complex one-liner removes any non-numeric columns like this:

> mycolMins(df[, sapply(df, is.numeric)])
$i
[1] 1

$f
[1] 1.2

$i2
[1] 3

Clearly converting that to a matrix while whole would result in everything
being converted to character and a minimum may be elusive.

Re: [R] Degree symbol as axis label superscript

[ani jaya]

one of my solution :

text(x,y,"\u00B0C", cex=1.1, font=2)

it will produce "°C"

text(x,y,"\u00B3C", cex=1.1, font=2)
it will produce "superscript(3)C"

so basically change the character after the "\u00B..." will produce
the superscript.

Best, Ani

David,

Absolutely nothing. When there's no specific degree value in the label
because the axis represents a range of values there's no digit preceeding
the ^ symbol.

The axis label is 'Temperature (oC)' with the degree symbol preceeding a
character, not following a specific digit.



There's nothing special about following a digit. You can have it follow 
anything. Since you were going to need to quote the parentheses anywa, 
then have it superscripted above the level of the paren:



plot(1,1, ylab = expression(Temperature~"("^degree*C*")")   )

Re: [R] Question about Rfast colMins and colMaxs

[Bert Gunter]

... but Rfast is *not* a "standard" package, as the rest of the PG
excerpt says. So contact the maintainer and ask him/her what they
think the best practice should be for their package. As has been
pointed out already, it appears to differ from the usual "read it in
as a data frame" procedure.

Thanks, Bill.

How do you go about getting maximum and minimum values from your 
columns? Do you simply do them one column at a time? The functions I am 
identifying from Rfast do this work in bulk.

Re: [R] Degree symbol as axis label superscript

[Bert Gunter]

True, but unnecessary with UTF-8 encodings of unicode (subject to some
caveats, though):

plot(1:5, runif(5),xlab = "Temp (°F)", ylab = "result")

should work fine, where the º ("degree") symbol was inserted by the
symbol insertion facility on my Mac. Windows has something similar.
See the comments in the plotmath documentation just before the
examples for more details on this, along with some caveats about the
need for a suitable display/plot device.

More laboriously, but perhaps more informatively, one can look up
"unicode code point for degree symbol" to find that it is decimal 176.
Then R's intToUtf8() function converts this to the UTF-8 encoding that
**should** display as a "degree" symbol, subject to the above
referenced caveats.
Hence:
> intToUtf8(176)
[1] "°"  ##degree character

## So, for example, you can do:
> degrF <-paste0(intToUtf8(176),"F")
> degrF
[1] "°F" ("degrees F")

> plot(1:5, runif(5),xlab = paste0("Temp (", degrF,")"), ylab = "result")

As Andrew said, you can use plotmath to do this, too; it just isn't
needed for simple insertion of "standard" symbols.

NOTE: As I am far from an expert on all of this, I would appreciate
clarification or correction of any errors or misstatements in the
above.

David,

Absolutely nothing. When there's no specific degree value in the label
because the axis represents a range of values there's no digit preceeding
the ^ symbol.

The axis label is 'Temperature (oC)' with the degree symbol preceeding a
character, not following a specific digit.

the use of the LaTeX ^ for a superscript
had a character or number preceeding it. Using 'degree' prints that

on the axis.

What does work is using the unicode for the degree symbol as prefix to
either C or F. In my case:
ylab('Water Temperature (\u00B0C)')
does the job.

I found this solution with the DDG search string, 'degree symbol in R

Re: [R] Degree symbol as axis label superscript [RESOLVED]

I think you have to not put the word degree in quotes, something like:


graphics::plot(
x = 1,

xlab = quote(
32 * degree
)

Re: [R] Question about Rfast colMins and colMaxs

[Jeff Newmiller]

I don't know anything about this package, but read.csv returns a data frame. 
How you go about forming a matrix using that data frame depends what is in it. 
If it is all numeric then as.matrix may be all you need.

Half of any R data analysis is data... and the details are almost always 
crucial. Since you have told us nothing useful about the data, it is up to you 
to inspect your data and figure out what to do with it.

Re: [R] Degree symbol as axis label superscript [RESOLVED]

On Tue, 30 Nov 2021, Rich Shepard wrote:


Thanks, Andrew. I will.


plotmath didn't have the solution; the use of the LaTeX ^ for a superscript
had a character or number preceeding it. Using 'degree' prints that string
on the axis.

What does work is using the unicode for the degree symbol as prefix to
either C or F. In my case:
ylab('Water Temperature (\u00B0C)')
does the job.

I found this solution with the DDG search string, 'degree symbol in R plot
axis label'. This stackexchange thread has the answer:

Re: [R] Question about Rfast colMins and colMaxs

[Bill Dunlap]

You can use as.matrix() to convert your data.frame to a matrix, but that
loses the speed/space advantages of colMins (as well as causing issues if
some columns are not numeric).  You could write to the maintainer of the
package to ask that data.frames be directly supported.  In the meantime you
could use
   vapply(yourDataFrame, which.min, FUN.VALUE=NA_real_)
or
vapply(yourDataFrame, min, FUN.VALUE=NA_real_)
instead of colMins.

Re: [R] Question about Rfast colMins and colMaxs

[Bert Gunter]

RStudio is **not** R. In particular, the so-called TidyVerse consists
of all *non*-standard contributed packages, about which the PG says:

"For questions about functions in standard packages distributed with R
(see the FAQ Add-on packages in R), ask questions on R-help.
[The link is:
https://cran.r-project.org/doc/FAQ/R-FAQ.html#Add-on-packages-in-R
This gives the list of current _standard_ packages]

If the question relates to a contributed package , e.g., one
downloaded from CRAN, try contacting the package maintainer first. You
can also use find("functionname") and
packageDescription("packagename") to find this information. Only send
such questions to R-help or R-devel if you get no reply or need
further assistance. This applies to both requests for help and to bug
reports."

Note that RStudio maintains its own help resources at:
https://community.rstudio.com/
This is where questions about the TidyVerse, ggplot, etc. should be posted.

[R] Degree symbol as axis label superscript

[Rich Shepard]

I want to present the temperature on the Y-axis label as 'Water Temperature
(oC)' with the degree symbol as a superscript.

My web search found a couple of methods; one put the entire example string
in the axis label, the other is close, but still incorrect.

Source example:
#define expression with superscript
x_expression <- expression(x^3 ~ variable ~ label)
# The example axis label is:
'X3 variable label' (with the 3 as a superscript)

My use:
# Set degree symbol as superscript in plot's y axis:
y_expression <- expression(^o ~ C)

R's error message:
Error in source("../scripts/all_temp_plots.r") :
  ../scripts/all_temp_plots.r:10:28: unexpected '^'
9: # Set degree symbol as superscript in plot's y axis:
10: y_expression <- expression(^
   ^

What is the proper way to display a degree symbol in a plot's axis label?

[R] Question about Rfast colMins and colMaxs

[Stephen H. Dawson, DSL via R-help]

Hi,


I am working to understand the Rfast functions of colMins and colMaxs. I 
worked through the example listed on page 54 of the PDF.


https://cran.r-project.org/web/packages/Rfast/index.html

https://cran.r-project.org/web/packages/Rfast/Rfast.pdf

My data is in a CSV file. So, I bring it into R Studio using:
Data <- read.csv("./input/DataSet05.csv", header=T)

However, I read the instructions listed on page 54 of the PDF saying I 
need to bring data into R using a matrix. I think read.csv brings the 
data in as a dataframe. I think colMins is failing because it is looking 
for a matrix but finds a dataframe.


> colMaxs(Data)
Error in colMaxs(Data) :
  Not compatible with requested type: [type=list; target=double].
> colMins(Data, na.rm = TRUE)
Error in colMins(Data, na.rm = TRUE) :
  unused argument (na.rm = TRUE)
> colMins(Data, value = FALSE, parallel = FALSE)
Error in colMins(Data, value = FALSE, parallel = FALSE) :
  Not compatible with requested type: [type=list; target=double].

QUESTION
What is the best practice to bring a csv file into R Studio so it can be 
accessed by colMaxs and colMins, please?

Re: [R] Is 'temp' a reserved/key word in R?

[Sarah Goslee]

Andrew is right - it's a typo.

More broadly, there's no restriction of that sort on the contents of
your data frame - reserved words can't be used for object names. The R
Language Definition is the best resource for identifying those words.

It would help if you provided the package for read_csv, since not
everyone uses tidyverse by default, although it isn't necessary for
this question.

Re: [R] Is 'temp' a reserved/key word in R?

[Micha Silver]

In header the row of the sample data file, the column names, "sampdate" 
and "param" are separated by a period, not comma. That would cause the 
error you're getting.

The response from R:
source('../scripts/test.r')
Warning message:
The following named parsers don't match the column names: sampdate, param

I searched the web to see if 'temp' is causing the problem and didn't find
an answer; my search term might have been flawed.

If that string is a problem please suggest an alternative.

Hi,

that is what I tried to show to Stefano. That the issue was only with printing 
the values on console or as you explained in more depth the default formating 
when all time values (HMS) are zero.

So that Stefano used correct syntax.

Cheers

That's not as.POSIXct doing anything:  there's no way to drop 
increments, the POSIXct format records a number of seconds and that 
can't be changed.


What is happening is simply the default formatting.

Be explicit about the format if you want to see the seconds, e.g.

> format(ssdf$data_POSIX, format = '%Y-%m-%d %H:%M:%S')

Dear R-list users,
I thought I was able to manage easily POSIXct, but this is not true.
I am not going to load the input txt file because I know that attachments are
not allowed. The structure of my input txt file is

data_POSIX,Sensor_code,value

I load it with
myfile <- read.table(file="mypath/myfile.txt", header = TRUE, sep=",", dec =
".", stringsAsFactors = FALSE)

When I try to convert the data_POSIX column (which is a character) to
POSIXct with

myfile$data_POSIX <- as.POSIXct(myfile$data_POSIX, format = "%Y-%m-%d
%H:%M:%S", tz="Etc/GMT-1")

the outupt is

2002-11-01 1694 7.2
2002-11-01 1723 10.8

Why I keep loosing hours, minutes and seconds? Wher eis my mistake or my
misunderstanding?

Sorry again if I have not been able to reproduce the R code, and thank you

Hi,
Petr is right. Apparently as.POSIXct drops the smallest increments if
all are zero:

ssdf<-read.csv(text="data_POSIX,Sensor_code,value
2002-11-01 00:00:01,1694,7.2
2002-11-01 00:00:00,1723,10.8",
stringsAsFactors=FALSE)
ssdf$data_POSIX<-as.POSIXct(ssdf$data_POSIX,"%Y-%m-%d HH:MM:SS")
ssdf

   data_POSIX Sensor_code value
1 2002-11-01 00:00:011694   7.2
2 2002-11-01 00:00:001723  10.8

but if there is a single small increment, they all show up.

Re: [R] converting to POSIXct

[PIKAL Petr]

Hi

You probably has zero hours in all your data

see
> temp
   data_POSIX Sensor_code value
1 2002-11-01 00:00:001694   7.2
2 2002-11-01 00:00:001723  10.8

without hours
> as.POSIXct(temp$data_POSIX, format = "%Y-%m-%d %H:%M:%S", tz="Etc/GMT-1")
[1] "2002-11-01 +01" "2002-11-01 +01"

add value to hours
> fix(temp)
> temp
   data_POSIX Sensor_code value
1 2002-11-01 00:01:001694   7.2
2 2002-11-01 00:00:001723  10.8

Voila, hours are back.
> as.POSIXct(temp$data_POSIX, format = "%Y-%m-%d %H:%M:%S", tz="Etc/GMT-1")
[1] "2002-11-01 00:01:00 +01" "2002-11-01 00:00:00 +01"

So nothing wrong in uyour code, hours are there but they are probably not 
printed to console and hours are there but hidden. 

Cheers
Petr

[R] converting to POSIXct

[Stefano Sofia]

Dear R-list users,
I thought I was able to manage easily POSIXct, but this is not true.
I am not going to load the input txt file because I know that attachments are 
not allowed. The structure of my input txt file is

data_POSIX,Sensor_code,value
2002-11-01 00:00:00,1694,7.2
2002-11-01 00:00:00,1723,10.8
...

I load it with
myfile <- read.table(file="mypath/myfile.txt", header = TRUE, sep=",", dec = 
".", stringsAsFactors = FALSE)

When I try to convert the data_POSIX column (which is a character) to POSIXct 
with

myfile$data_POSIX <- as.POSIXct(myfile$data_POSIX, format = "%Y-%m-%d 
%H:%M:%S", tz="Etc/GMT-1")

the outupt is

2002-11-01 1694 7.2
2002-11-01 1723 10.8
...

Why I keep loosing hours, minutes and seconds? Wher eis my mistake or my 
misunderstanding?

Sorry again if I have not been able to reproduce the R code, and thank you for 
your support.
Stefano
