I have a list of strings of different lengths and would like to split each
string by underscore "_"
pc_m2_45_ssp3_wheat
pc_m2_45_ssp3_wheat
ssp3_maize
m2_wheat
I would like to separate each part of the string into different columns
such as
pc m2 45 ssp3 wheat
But because of the different lengths - I would like NA in the columns for
the variables have fewer parts such as
NA NA NA m2 wheat
I have tried unlist(strsplit(x, "_")) to split, it works for one variable
but not for the list - gives me "non-character argument" error. I would
highly appreciate any help. Thank you!
