Hi all,
I have a problem with checking File is present in the directory or not
like
I have a sequence of files in one folder I have to take each file in
order
and have to caliculate on those files data but in order some files are
missing for that I have to check and load those files for that I am
using
condition like
if(file.exists(findings)==TRUE){}
What is "findings"? Have you defined it elsewhere? What was the code?
Is findings a properly constructed file name for R's interaction with
whatever filesystem you are using?
> file.exists( file="/Users/davidwinsemius/Documents/R_folder/
actuar.pdf")
[1] TRUE #would have been FALSE if only the file name was used, since
that is not my working directory.
its giving results for files which are present in that folder
but for files which are not present in that folder its giving error
but it have to skip and run for remaining files
And am unable to reproduce the problem with a similar call.
> file.exists("xyz")==TRUE
[1] FALSE
You should note that file.exists returns a logical vector, so the
comparison with TRUE is superfluous.
can any one suggest any other way to make it work
for all those files
Without more specifics it's not possible to reproduce your problem.
Include full code and the results of sessionInfo.
?sessionInfo
thanks in advance
