Hello everyone,
I am a beginner in R.
In order to verify my data files (which are tables with values separated by
spaces in .txt files), I wanr to count the number of columns in each file.
So I made the formula that works:
ncol(read.table("my_file.txt", header = FALSE, sep = ""))
The problem is I have 257 files to check in the same folder! I would have to
automate this function for me to get the number of columns in each of his
files.
I think I shoud use this formula :
list.files(path="C:/.....")
But I don't know how to...
Could you help me ?
Thanks.
