I have a table in R which consists of 70k rows and 37 columns. Lot of cells have "./." which I want to modify and make it as "ab" . I tried to use
gsub() but it does not give me the required output.
I used :
file <- gsub("./.","ab",file)
I want the change to happen throughout the file. Is there any other way with which I can modify it? Thanks in advance.
S.no chr pos gene_name S1 S2 S3 1 1 1290 X ./. 1/1 ./. 2 1 5822 Y 0/1 ./. ./.
S.no chr pos gene_name S1 S2 S3 1 1 1290 X ab 1/1 ab 2 1 5822 Y 0/1 ab ab
It can be either ab or NA
