Hi,
With the following codes, I attempt to convert
the data.frame into a matrix.
However I notice that data.matrix function doesn't
seem to work.
__ BEGIN__
dat <- read.table("mydata", comment.char = "!" , na.strings = "null");
# Select n-genes by random sample
# n = 1
nosamp <- 1
geneid <- sequence(nrow(dat))
geneid.samp <- sample(geneid,nosamp)
geneid.samp
gexp<- dat[geneid.samp,]
gexp.arr <- data.matrix(gexp, rownames.force = NA)
print(is.matrix(gexp.arr))
print(gexp.arr)
__END__
Yielding this output:
__BEGIN__
> print(is.matrix(gexp.arr))
[1] TRUE
> print(gexp.arr)
V1 V2 V3 V4 V5 V6 V7 V8
10354 803.1 1107.8 431.6 349.8 386.7 646.3 744.2 620.9
__END__
I expect "gexp.arr" to be a plain vector (numeric).
What's wrong with my code above?
