Re: [R] how to get list of files within a particular local file folder
How you read all ... files is up to you, as that depends both on the type of data contained in the files and on how you plan to use the data. Most likely the solution will involve using the files.list function and either lapply or a for loop, and the data will end up stored in a list of data objects. (If the data are tabular you might use the sapply function to create a single data table.) --- Jeff NewmillerThe . . Go Live... DCN:jdnew...@dcn.davis.ca.usBasics: ##.#. ##.#. Live Go... Live: OO#..

Dear Ajay Ohri,
Re:
Dear List,
Say I can use getwd() and setwd() to change my working directory. How can I
read in all the files within that directory using command line (like a ls()
but for the path specified)
I use this function,
# functions
getFolder - function(pat)
{
txt=file.choose()
#cat(txt,'\n')
pos=0
fname=basename(txt)
#cat(paste(\nFilename found is: ,fname,'\n'))
foln = dirname(txt)
cat(paste(\nFolder name found is: ,foln,'\n'))
drtext=dir(foln, pattern=pat, full.names = TRUE)
#cat('\n\n\n\n')
return(drtext)
}
Best,
Franklin
