I\'ve been figuring this out for a couple of hours now. Let\'s say I have a column with 1-4 words, separated by space:

aba bkak absbs
a2aj akls bios
sad
fasa

    With the devel verison of data.table could also do

    library(data.table) # V >= 1.9.5
    setDT(df)[, tstrsplit(V1, ' ')]
    #      V1   V2    V3
    # 1:  aba bkak absbs
    # 2: a2aj akls  bios
    # 3:  sad   NA    NA
    # 4: fasa  lgk    NA
    

    Or with stringi (though you'll get a matrix back)

    library(stringi)
    stri_split_fixed(df$V1, ' ', simplify = TRUE)
