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:
1) transpose
2b) as.data.frame with stringsAsFactors= FALSE
3b) convert to numeric

"pressurization"

How do I convert rows 1-5 to numeric? I tried mode() <- "numeric"
but that doesn't change anything.
I also tried converting this to a table then converting to numeric,
but I got: (list) object cannot be coerced to type 'double'
