Dear all, Does any one know how to remove part of the string? For example, "LTA4H||Leukotriene A4 hydrolase" is a gene name plus gene description. I hope to remove "||Leukotriene A4 hydrolase". What would be the R code to do that using gsub()? Many thanks! Bill
Hi. You can do something like this:
gsub("\\|\\|Leukotriene A4
hydrolase","","LTA4H||Leukotriene A4 hydrolase")
