Hi,
Try this:
dat1 <- readLines(textConnection("Granitic Hills 16-20 PZ
Loamy Upland 16-20 PZ
Sandy Loam Upland 12-16 PZ / Sandy Loam, Deep 12-16 PZ
Loamy Upland 12-16 PZ / Sandy Loam Upland 12-16 PZ
Loamy Upland 16-20 PZ"))
dat3<-strsplit(dat1,"/")
data.frame(col1=do.call(rbind,lapply(dat3,`[`,1)),col2=do.call(rbind,lapply(dat3,`[`,2)))
# col1 col2
#1 Granitic Hills 16-20 PZ <NA>
#2 Loamy Upland 16-20 PZ <NA>
#3 Sandy Loam Upland 12-16 PZ Sandy Loam, Deep 12-16 PZ
#4 Loamy Upland 12-16 PZ Sandy Loam Upland 12-16 PZ
#5 Loamy Upland 16-20 PZ <NA>
A.K.

Subject: [R] irregular splits in dataframe
Hello everyone,
My dataframe (Soil Type) looks something like this
Granitic Hills 16-20 PZ
Loamy Upland 16-20 PZ
Sandy Loam Upland 12-16 PZ / Sandy Loam, Deep 12-16 PZ
Loamy Upland 12-16 PZ / Sandy Loam Upland 12-16 PZ
Loamy Upland 16-20 PZ
I want to separate them at "/", but when there is just one type, I want "NA" in
the second column, How can I do that ??
Thank you
