Hi Rui,
I use the code to fix my problem:
try$newcol <- gsub(" NA", "", try$newcol)

But, I'll try your solution later.
Thank you for your help.

 Hi List,
I use paste function to concatenate  3 character columns together.
when I run table to see that, I found 3 categories. How can I write script to trim NA in 2nd and 3rd group and set the first one as NA?
NA NA Adenocarcinoma
NA Other NA
