[R] ggplot - position=position_dodge()) and scale_y_continuous

2019-07-30 Thread Knut Krueger via R-help 

Hello to all,

how can I can set both  y as character to get the bars beside like 
example 1 and  use scale_y_continuous


And an additional question: why are the bar colors of  x-axes = 8 turned

datax= data.frame("fac"=c(c(rep(1,10),c(rep(2,10,"x"=c(c(1:10,c(1:10))),
   "y"=c(89,69,46,57,43,5,83,35,15,19,
 51,16,36, 4, 3,3,77, 5,30,61))


ggplot(data=datax, aes(x=x, y=as.character(y), fill=fac)) +
  geom_bar(stat="identity", color="black", position=position_dodge())+
  theme_minimal()+
  scale_x_continuous(breaks=c(1:12)) #+
 # scale_y_continuous(limits=c(0, 100))


ggplot(data=datax, aes(x=x, y=y, fill=fac)) +
  geom_bar(stat="identity", color="black", position=position_dodge())+
  theme_minimal()+
  scale_x_continuous(breaks=c(1:12)) +
scale_y_continuous(limits=c(0, 100))

It should be simple but i do not find the right keywords:


Dup =  c(1,2,3,4,1,2,3,5)

I need 4,5 as result

unique(Dup) gives me [1] 4 1 2 3 5

duplicated(Dup) gives me
[1] FALSE FALSE FALSE FALSE  TRUE  TRUE  TRUE FALSE

I need
[1] TRUE TRUE TRUE FALSE  TRUE  TRUE  TRUE FALSE

There is an

why is there f.e no %!in%, %notin%  or !%in%

Re: [R] "logical indexing, " [was] match() question or needle haystack problem for a data.frame

2018-10-25 Thread Knut Krueger 

Hi Bert,
another question for indexing
1. is there a good manual  for indexing

2.  is it possible to get !%in%
f.e
x =data.frame("A"=c(1:5),"C"=c("A","B","C","D","E"))
y =data.frame("B"=c(1,3,5))
test = x[x$A %in% y$B,]
test = x[x$A %in% y$B,]

test
A C
1 1 A
3 3 C
5 5 E


means: the result where I am looking for is:
test
A C
2 2 B
4 4 D

no problem with a loop but in a short way I do not find a solution

Hi Bert,

especially the "match" help area is a little bit confusing.

And additional using a couple of programming languages with different

So the logic operations itself are not mysterious ;-)  but the

And thank's a lot to give me the keyword to find for what I am was

match(Mydata$DATA1, needles, nomatch=NA) does find all data which are in 
needle - the others are set to the nomatch value.


But I don not find out how to reduce the data.frame  -  maybe match() is 
not helpful for that.

[R] subset only if f.e a column is successive for more than 3 values

2018-09-27 Thread Knut Krueger 

Hi to all

I need a subset for values if there are f.e 3 values successive in a 
column of a Data Frame:

Example from the subset help page:

subset(airquality, Temp > 80, select = c(Ozone, Temp))
29 45   81
35 NA   84
36 NA   85
38 29   82
39 NA   87
40 71   90
41 39   87
42 NA   93
43 NA   92
44 23   82
.

I would like to get only

...
40 71   90
41 39   87
42 NA   93
43 NA   92
44 23   82


because the left column is ascending more than f.e three times without gap

Any hints for a package or do I need to build a own function?

[R] counting similar strings in data.frame

Dear Members,

is there a better solution to count the amounts of occurrence in a row 
with string data than with loops to get the count data.frame?


test =data.frame(first=c(seven,two,five,four),
 second=c(three,one,three,one),
 third=c(four,two,three,four),
 fourth=c(four,one,one,four))



count =data.frame(double1=c(four,two,three,NA),
 double2=c(NA,one,NA,NA),
 triple=c(NA,NA,NA,one))


double1: first double occurrence in row  (NA if triple available)
double2: second double occurrence in row (NA if triple available or if 
there is only one double)

triple: triple occurrence in row (NA if a double available)

@David and @Bert

unfortunately yes. My question is more a system level question as about 
any converting functions.


The question is how to paste a windows path directly into an R script 
(without readline() or readClipboard() and how could I convert this 
string that it is usable in R. Means any function which is not using 
escape characters


it seems to be possible for readline() an  readClipboard().

I do not want to use y=readline() I do want to use 
y=foo(c:\foo1\foo2\) but this seems to be impossible because R is 
interpreting one backslash as escape sequence. So how does readline() 
and readClipboard() are working? Is there any other callback from utils 
which is able to deal with this?


I am afraid there is no way.

The reason is to prevent errors for beginning windows R user. If the 
path is long they either forget to convert one backslash or all and then 
they are frustrated that it is not working. And telling them to use 
search and replace ... Whatever they would replace it might be worse 
than before ;-)

You were already advised how to change the defaults for R's input functions'

ither change comma to dot in Excel (but sometimes Excel is rather reluctant to

Thats also impossible because the data are lost after teh import

is optional parameter and maybe it is also readWorksheet.

Read data has no problem

No. This is more a sign of your lack of experience with R. There are wiki-pages 
with advice about various ways to do Excel input. (You surely cannot think you 
are the first to experience this. This has been a difficulty for 15 years, and 
more with Excel than with R.)


Once again I have no problems to get the data inside R but I am looking 
for a solution to get an error message instead of setting 0,25 to na and 
only i a few column not in the hole sheet. That's a behaviour what I am 
expecting from MS not from R
But I got definitely wrong inputs with lost data with loadWorkbook. But 
it is not reproducable. doing the same  with a fresh environment,not 
after working 5 hours with R,  the excel sheet is imported without 
error. I am no a newbie in R and i am using it nearly 10 years. Them 
same problem occoured with RCmdr in the university by a phd Student. I 
can not reproduce the problem with the same script and the same file. 
Maybe you can agree that this is strange. Its a kind of never be sure 
to get the correct data and that happened to me the first time with R.

read table is not able to read xls and xlsx files

I found the reason there are NA inside the column but
  gdata  read.xls  is doing the job fine, but it needs the perl

  also Rcmdr has also no problems with NA in a decimal data column
  readWorksheet does the job also when no NA is in the column and with

Thanks for the package it is very useful .. but I did not solve my problem.

As I have not much time I tried some basic configuration but the

Its more easy for beginners to use the column notation than the row

Therefore I must count the Items of the string separated by , or

What do you mean by better?

Dear Peter

Thank you for your kind respons as well. You are right, we are in
constant debate whether it makes sense to remove variables (no matter
whether significant or not) from a total dataset which in itself has a
certain meaning and may not stand for other studies with differing
variables.

However, in biology it is common practice to remove non significant
factors (and sometimes also variables)from data sets (so called: forward
and backward elimination process), usually when they are permanently non
significant on all the paticular positions in the factor list.

Some authors suggest only to remove data which may have similar meanings,
and therefore may be understod as pseudorepliaions.

[R] sum(row1==y) if row2=x

2009-11-13 Thread Knut Krueger 

Hi to all
is there any construct to sum
data=data.frame(row1=c(1,1,3,1,2,3,2,2,1,3,4,5,2,3,2,1) ,
 row2=c(2,2,1,1,1,2,1,2,1,1,1,1,2,2,2,1) )
Means I would like to get all y of row1 if in row2 of the data.frame is 
an x

f.e row1=3 and row2=2
so I would like to get 6

And is there another construct to get the count of pairs where
row1=3 and row2=2
means the result should be 2
I could do this with loop but I am wondering whether there is any better 
way.

Any solutions?

System

R 2.8.1
Tinn-R 2.2.02
windows Xp professional Servicepack 3

This combination works on my Pc without problems
And the code is working on the other system with Tinn-R problems
with the R-Editor without problems
so it seems to be a Tinn_R problem

but maybe anybody has a solution for that.

Hi,

using a variable named .trPaths is a feature and a frequent nuisance 
of recent Tinn-R and also explained in the Tinn-R docs.


Solution 1:

In Tinn-R select the menu:

 R -- Configure -- and then Temporarily or Permanent

Solution 2:

Manually edit file R-installation-directory/etc/Rconfig.site

The minimal line to add is:

.trPaths - paste(paste(Sys.getenv('APPDATA'), '\\Tinn-R\\tmp\\', 
sep=''), c('', 'search.txt', 'objects.txt', 'file.r', 'selection.r', 
'block.r', 'lines.r'), sep='')



Hope it helps


no for me - I do not switched to permanent and i did not have the 
Rconfig.site file edited but it is working

So i do not know *why it is working* ;-)

I hope yes for the others (I will forward it) on the computers where it 
is not working


Thank you Knut

Hi Uwe,
I was just asked the same question and hat the same problem before. It 
seem that it is a Tinn_R installation problem
. I do not now what I changed to get it working, but the single line (R 
send line) mode is working, the

R send selection and Rsend file mode not.

System Windows XP new installed TinnR File permissions should not a 
problem on windows systems. Maybe any file is set to read only?


The same srcipt which is working at home is not working at the new system.

You can set 'curved' to a value close to zero and then the arrows will
be only a bit curved.

Its a very

I am a bit lost. What formula are we talking about?

I tried to get the starting point of the arrows depending on the

Hmmm, how should 'plot' know automatically what size/width you want?
Sorry, I don't really know what you want to achieve here. If you want
to calculate the width from some properties of the graph, then simply
do that and assign it as the 'width' argument.

  

Hi Gábor,
the radius of the circle is representing the numbers of actions of the 
node to all other nodes.
I need an additionally information about the numbers of actions 
*between* the nodes differentiated by the direction from and to the nodes.


Example
Node 1 - 2  1 actions
Node 2 - 125 actions
Node 3 - 1 4 actions
Node 1 - 3   10 actions
Node 2 - 3 5 actions
Node 3 - 2 2 actions

I am looking for any graph which shows the direction and counts of the 
actions with f.e different thickness of the arrows,
It must be  viewable 
http://dict.leo.org/ende?lp=endep=thMx..search=viewable that the 
actions from Node 2 to Node 1 are much more than from Node 1 to 2 and 
also more then from node 3 to three, and so on.


Maximum nodes: about 20

Follow along these lines:
http://lists.gnu.org/archive/html/igraph-help/2009-04/msg00104.html
plus set the 'width' edge attribute to represent the number of actions.

  


Thanks,Gabor
this was my first solution, but unfortunately the data are very 
complicated to visualize.

let me expand the example:

Example
Node 1 - 2 1 actions
Node 2 - 125 actions
Node 3 - 1 4 actions
Node 1 - 325 actions
Node 2 - 3 5 actions
Node 3 - 225 actions

In that case all lines would be thick and the actions Node 1 - 2  ,Node 3 - 1,Node 2 - 3   would be invisible, so I tried the narrow arrows to get above the thick arrows in an other colour, but I found no rule to order them that the are always on the top 
... and the team was not satisfied with this suggestion ;-)


The would prefer two parallel arrows one for each direction. Its a very  
long mathematical formula to display those arrows, depending on the 
radius of the circles, and there is a ...hidden...error in the formula.




So I tried to ask again if there is another solution.

By the way: Do you know such arrow funtion: arrow(starting_point, angle, 
length) ?


Thanks's for your patient

2. is it possible to change the thickness of the lines depending of the

It depends what you mean by 'automatically'. 
  
means: Do I have to calculate by myself that there are 
4 1 0

2 2 1
1 20
1 13
or is there any switch to set  the different V(g)$size and E(g)$width
to get the following result:

iigraph_data -c(1,0, 1,0, 1,0, 1,0, 2,1, 2,0, 2,1, 1,3)
g - graph( igraph_data,n=max(igraph_data), directed=TRUE )
V(g)$size - c(40,20,10,10)
E(g)$width - c(4,4,4,4,2,1,1,1)
E(g)$arrow.size - 1
