Re: [R] Splitting strings
This applies the indicated perl-style regular expression where the
first backreference (\\D+) is the non-digits and the second
backreference (\\d+) is the digits.
The two backreferences, but not the entire matched pattern itself,
are passed as arguments x and y to the function whose body is the
right hand side of the formula in the third argument.
That is then simplified using rbind to give the result.
library(gsubfn)
strapply(surgery, "(\\D+)(\\d+)", ~ list(lets = x, nums = as.numeric(y)),
backref = -2, perl = TRUE, simplify = rbind)

Re: [R] Splitting strings
one way is the following:
data.frame(status = gsub("[0-9]", "", surgery),
time = gsub("[a-z]", "", surgery))
I hope it helps.

[R] Splitting strings
I'm having a Thursday morning mental block, any suggestions on the following
would be most appreciated...
I have (as an example)
surgery = c("d48", "d67", "dnc37", "a75", "d10", "a78", "d31",
"d55", "d1")
before each number part the possibilities are c("a", "d", "dnc"), I'm trying
to split each element in "surgery" so that I have,
status time
d48
d67
dnc 37
a75
d10
a78
d31
d55
d1
I've tried various strsplit approaches but nothing has done what I need.
thanks in advance
Gary
