Hi,
I'm looking for some way to pick up the numbers which are contained and buried
in a long character.
For example,
outtree.new="(((B:1204.25,E:1204.25):7581.11,F:8785.36):8353.85,C:17139.21);"
num.char =
unlist(strsplit(unlist(strsplit(unlist(strsplit(unlist(strsplit(unlist(strsplit(outtree.new,")",fixed=TRUE)),"(",fixed=TRUE)),":",fixed=TRUE)),",",fixed=TRUE)),";",fixed=TRUE))
num.vec=as.numeric(num.char[1:(length(num.char)-1)])
num.char
# "B" "1204.25" "E" "1204.25" "7581.11" "F" "8785.36"
"8353.85" "C" "17139.21" ""
num.vec
# NA 1204.25 NA 1204.25 7581.11 NA 8785.36 8353.85 NA
17139.21
would help me get the numbers such as 1204.25, 7581.11, etc, but with a warning
message which reads:
"Warning message:
NAs introduced by coercion "
Is there a way to get around this? Thanks!
Hua
