I have microarray data with gene names in the first column, gene id in the
second and the expression data in the remaining columns. When trying use
read.table I get the error, . . . "more columns than column names". Is
there any way to keep both columns of "names" without having to discard one.
or the other? The raw data is read from a text file and is in the form
mitogen-activated protein kinase 3 1000_at 946 1928.8 1504.9 722.5
873.9
836.9 1294.3 631.1 606 1126.6 841.2 833.6 689.6 1256.9 685.8
755.3 974.8
where, mitogen-activated protein kinase 3 is the first column of this (tab
delimited) text file and 1000_at is the second column. I want to keep both
columns as labels. Is there a way to do that?
I've used:
test <- read.table("<path>", header=T, sep="\t", row.names=1)
and get the error, more columns than column names.
Many Thanks,
