Hi,
Slight modification to my earlier code to make it more simple.
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(do.call(rbind,lapply(dat3,`[`,c(1,2))))
#??????????????????????????? X1????????????????????????? X2
#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>

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
