How to replace the specific ‘NA’ value (not all ‘NA’) to the specific numerical value in R data frame?

I have a large data frame which has more than 500 rows and 40 columns like; dataframe <- data.frame(ID=c(“ID1″,”ID2″,”ID3″,”…”), column1=c(1,NA,0,1), column2=c(1,0,0,1),column3=c(1,NA,NA,NA),… = c (1,0,1,1)) Now in column 3, there are three ‘NA’ values, and I want to replace column3 of ID2 to numerical value ‘1’. Please tell me the good way to do so.
