I have a matrix that looks like this:
structure(c(0.0376673981759913, 0.111066500741386, 1, 1103,
18, OPEN, DEPR, 0.0404073656092023, 0.115186044704599,

How about
Matrix[1:5,]=as.numeric(Matrix[1:5,])

Subject: Re: [R] Convert matrix to numeric
How about
Matrix[1:5,]=as.numeric(Matrix[1
Here's what you _should_ do
1) transpose
2a) as.data.frame
3a) fix the stupid default stringsAsFactor behavior
4a) convert the first 5 columns to numeric
dfrm - as.data.frame( t( structure(.) ) )
dfrm[, 1:5] -lapply(dfrm[, 1:5], as.character)
dfrm[, 1:5] -lapply(dfrm[, 1:5], as.numeric)
Or:
6 matches
