Hello
I have a data frame and one of its columns is as follows:
Col
chr1:71310034
chr14:23354088
chr15:37759058
chr22:18262638
chrUn:31337214
chr10_random:4369261
chrUn:3545097
I would like to get rid of colon (:) and replace this column
with two new columns containing the terms on each side of the colon. The new
columns
should look as follows:
Col_a Col_b
chr1 71310034
chr14 23354088
chr15 37759058
chr22 18262638
chrUn 31337214
chr10_random 4369261
chrUn 3545097
Any help will be much appreciated
Joseph

try this:
dat <- data.frame(Col = c("chr1:71310034",
"chr14:23354088",
"chr15:37759058", "chr22:18262638",
"chrUn:31337214",
"chr10_random:4369261", "chrUn:3545097"))
vals <- strsplit(as.character(dat$Col), ":")
dat$"Col_a" <- sapply(vals, "[", 1)
dat$"Col_b" <- as.numeric(sapply(vals, "[", 2))
dat
I hope it helps.
