[R] Keep only those values in a row in a data frame which occur only once.

Dear All,

I have a file data.txt as follows:


I will read this with:
my_data<- read.csv("data.txt",header=FALSE,col.names=paste0("V",

Then the file will have 10 columns. I am assuming that each row in data.txt
will have at the max 10 entries.

Note: Here each row will have a different number of columns in data.txt but
each row will have 10 ( some trailing blank columns ) columns.

My query is how can I keep only the unique elements in each row? For
example: I want the row 3 to be Name_3,I,J,K,L,M

Please note I don't want the 2nd I to appear.

How can I do this?

Best Regards,
