Hi, I'm trying to run a GAM regression in mgcv with:
1. My own knots(which I learned to do here
https://stat.ethz.ch/pipermail/r-help/2012-December/342723.html)
2. One of the cubic splines is defined as monotonic increasing

Hello,
I'm a R beginner and I want to make a Multiple Regression about birds. My data
is stord in a .csv file.
I tried to do this with the following code:

names(reg.data)

I am trying to incrementally add rows to an empty data frame. The data has 7
columns, the last 6 are numeric.
For the first columns I would like to include a text identifier, called
‘Case’ like Andrew, Burt, Charlie etc. that is also output to a data frame –
this is where I am having the problem

One way to see where the first warning comes from is to turn warnings
into errors with options(warn=2) and when the error happens call
traceback().

Inp_dat- read.csv(/File/Input data.csv)
out_put[i,]-data.frame(Case, stdL, stdPP, stdSE, L, PP, PP_SE)
These two statements look like the source of the problem.
Add the optional argument
stringsAsFactors=FALSE
to both.

please stay on list. I am returning this to the list.
David's comment that b is never used might be relevant.
I think the next step is for you to post a small dataset that causes the problem
dput(head(Inp_dat))
might be enough.

I'm just getting into working with SQLite databases using the RSQLite

long due to poor optimization, and want to make sure when I

Dear all,
I am a user of R Studio, which I appreciate very much.
Recently I have changed my pc and I am having some problems to use R Studio.
I have finally manage to make RStudio work today.
However, to do that I am opening it with R x32 as a default. This is a bit
strange for me because I have
If you really prefer solution code, then provide reproducible example code as
the footer requests.
Use ?merge with the all.x=TRUE parameter, and then perform your calculations on
the resulting combined data frame, using ?ifelse and ?is.na as needed.
Wrong forum. RStudio has its own community support forum at their website.

what's the difference between [:space:]+ and[[:space:]]+ ?
The pattern '[:space:]' matches any of ':', 's', 'p', 'a', 'c', and
'e' (the second colon is superfluous). I.e., it has no magic meaning.
Inside of [] it does have a special meaning.
The pattern '[[:space:]]' matches a space, a
you can get a new data frame by
merge(qpiso, qplegit, all.x = TRUE, all.y = TRUE, by = iso )

For the t-test, you used the two-tailed t-test. It is the default. Here I
think you should set alternative=less in the t.test function.

I created the following file:
symbol,shares
XOM,1000
APA,400
CVX,200
I then read the file in R using the command:
stockList=read.table(/NotesOnR/stockList, header = T, sep=,)
I would then expect the following expression to evaluate to the simple
string APA:
stockList$symbol[2]
Thanks,
I then set NA to 0, and can do the sutraction,
great.

Not so great. I haven't gone through the issues underlying this post,
but replacing NA by 0 will almost surely yield nonsense. Missing is
***not*** the same thing as zero.
Thank you very much.

then disappears.

Good Evening,
I'm a graduate student working on a project looking at issues with R
package submission and maintenance; specifically looking at the discovery
and elimination of functional/failure package errors (i.e. does the package
do what its supposed to do? is the underlying math correct?).
Dear R-help,
I am working with some data stored as filename.txt.gz in my working
directory.
After reading the data in using read.table(), I can see that each of them
has four columns (variable, id, outcome, and rate) and the following
