Using the readlines function on your dat string gives the error because it is looking for a file named "2 3 ..." which it is not finding. more likely what you want is to create a text connection (see ?textConnection) to your string, then use scan or read.table on that connection.

It is a bit unclear from your posting exactly what your data
is. I'm assuming that you have an R dataset, a single character
string called Data, made with a command like
Dat = "1 2 3 4 5
6 7 8 9 10
11 12 13 14 15"
(If you have a file, say "Dat.R", containing those three lines of text
then
run source("Dat.R") and you be in the above situation.)
I'm also assuming that you want to intuit the number of columns
in the matrix from the layout of numbers in the string contained
in Dat.
Your string contained blank lines between every "real" line.
I suspect someone's mailer put them there, but you can get
rid of them with
tDat <- gsub("\n+", "\n", Dat)
Next, break your string into "lines" and then each line into
"words"
so you can count the number of entries in each line and make sure
there are the the same number of entries in each line.
lines <- strsplit(tDat, "\n")[[1]]
words <- strsplit(lines, "[[:space:]]+")
nWordsPerLine <- unique(vapply(words, FUN=length, FUN.VALUE=0))
stopifnot(length(nWordsPerLine) ==1)
Finally, convert the "words" to numbers and make the matrix
m <- matrix(as.numeric(unlist(words)), ncol=nWordsPerLine, byrow=TRUE)
print(m)
[,1] [,2] [,3] [,4] [,5]
[1,] 1 2 3 4 5
[2,] 6 7 8 9 10
[3,] 11 12 13 14 15
