Hi list,
I have a question about using *read.table()* to read in a txt file.
Basically, it
consists of 16346 rows, 6 columns (no header). The code I used is:
exprSet <- read.table('process_all4_GSA2.txt', row.names = 1,header =FALSE)
and I got an error message:
> exprSet <- read.table('process_all4_GSA2.txt', row.names = 1,header
=FALSE)
Error in read.table("process_all4_GSA2.txt", row.names = 1, header = FALSE)
:
duplicate 'row.names' are not allowed
In addition: Warning message:
In read.table("process_all4_GSA2.txt", row.names = 1, header = FALSE) :
incomplete final line found by readTableHeader on 'process_all4_GSA2.txt'
However, I have no problem with the code to read in a similar txt file which
consists of 22277 rows, 72 columns.
> exprSet <- read.table('70mel_GSA.txt', row.names = 1,header =FALSE)
> dim(exprSet)
[1] 22277 71
> exprSet[1:4,1:4]

GENE2 RFC2 8.028489 8.175520 9.090902
GENE3 HSPA6 4.633769 4.822625 5.125172
GENE4 PAX8 6.121433 6.396281 6.000987
The two txt files are of similar format. The only difference so far I can
tell is that
the second file is of more rows and columns. Other than that, they are
basically
the same. But I don't know what is the issue with the first txt file.
Thank you so much for your help!
