[R] irregular splits in dataframe

[arun]

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
