Hi.
Is there a straightforward way to convert a character string
containing comma-delimited
numbers to a numeric vector?
In my application, I use
system(executable.string, intern=TRUE)
which returns a string like
"[0.E-38, 2.096751179214927596171268230,
3.678944959657480671183123052, 4.97

Hello everybody
thanks for the tips.
I *think* this should be the same thread
The manpage for system() says that lines of over 8095
characters will be split. This is causing me problems.
How do I get round the 8095 character limit?
Simple toy example follows:
jj <- system("echo 4 | aw

Here is one way. This matches strings which contain those characters
found in a number, converting each such string to numeric.
library(gsubfn)
strapply(x, "[-0-9+.E]+", as.numeric)
