Dear R help list,
I am very new to R and I apologize in advance if this has been answered
before. I have done my best to google/R search what I need but no luck.
Here is what I am attempting:
I have hundreds of .csv files that I need to sort based on a single column
of alphanumeric data. All of the files contain matrices that have
identical dimensions and headers, however the data table doesn't begin
until the 74th line in each file. Doing some searching, I have been able
to create an object with elements consisting of each file in the folder
containing the targets (please note this is my working directory):
filenames<-list.files()
alldata<-lapply(filenames, read.csv, skip=73, header=TRUE)
At this point I believe I have created an object with N elements (where N=#
files in the wd), each containing the matrix I am attempting to sort. I am
completely lost as to how I can sort each matrix based on a single column
(say, "Name") and then either overwrite the source files or write to a new
directory all of the sorted data. I half wonder if I should be creating
individual objects for each file that I read in, but I haven't been able to
figure this out either. Please note that I am trying to sort these files
individually - would a loop be more efficient?
I appreciate the help,
BustedAvi
