Hi everyone, I am having trouble understanding where I went wrong with my
code. It seems to logically be "all there" but the output says otherwise.
I know this is a bit long but I can't seem to find the errors so I would
appreciate your help :)
This is my program :
files<-Sys.glob("*.rescount.txt");length<-length(files);* #selecting all
files of a particular extension, saving in a list*
Your use of the name 'length' is a bad idea (but not your problem);
see fortune("dog").
If you think that your object 'files' is a 'list', you're mistaken;
try str(files) to see that it's a character vector.
a<-1;
while(a<=length) *#going through every element of the list*
{
df1<-read.table(files[a]);
I would _always_ look at the result of any file import with str() to
ensure that the reading went as expected. Do (some of) your files have
variable variable name headers?
c.leng<-length(files[,1]);
I don't see why this instruction would not throw an error re "incorrect
number of dimensions".
Okay, at this point I gave up. Your code is not reproducible and
you're posting in HTML. Please give at least a cursory look at the
Posting Guide.
