Hi I want to import around 75 files. Each file has a name and a time and is
comma separated.
For example some of my file names are
Asheville_Dec.txt
Asheville_Jan.txt
Asheville_Feb.txt
Charlotte_Dec.txt
Chapelhill_Jan.txt
The time months are only Dec Jan and Feb. The locations are different. I
Hello everyone,

the archives for help with no luck. I am trying to perform a regression on a

predictors. I have 100 response variables collected
Hi
Best way is to put those files in one directory and start R from this directory
or set this directory as working one.
?set.wd
Then you can use list.files() to get file names.
?list.files
myfiles-list.files()
Than strip txt. E.g. by
filenames-strsplit(list.files(), \\.))
After that you
Hm. We also do not know what will be done with those files. Save/load is an
option but in that case nothing prevents you to use original file and read.*

I understood that OP wanted to load all files as 75 objects into one R session
environment. In that case having one

I've been using the randomForest package and I'm trying to make the switch

32-bit or 64 bit operating system?
RAM is cheap but will your motherboard support more than 4 GB?
And don't forget there are other processes that need to run while you are
using R.

Perhaps you will understand the meaning better if you try the following
sequence:
plot(datalist, ylab='Value')
lines(lowess(datalist),col=blue, lwd=2)

Unfortunately, this does not solve my main issue, that is:

Please read the posting guide (there is a link at the bottom of every
post) and post in plain text, not HTML, and also avoid all caps.
The biggest repository of R code is probably CRAN which is linked from
the main R page. There are also R-forge and Bioconductor and many R
packages on Github.
Look into the while() statement. E.g.,
f - function(n, absLimit)
{
x - rep(absLimit+1, n) # start with all x,y outside limits
y - x
while(any(isOutside - abs(x)absLimit | abs(y)absLimit)) {

You're specifying a string rather than two numbers.

This is really a question of programming logic - not of R per se.
If I understand your problem correctly, the preferred approach is not to create
your paths all at once, but individually, and check that they fulfil your
requirements as you generate them. Keep on doing this until you have enough
