Handling empty cell values in R for logistic regression

Question

I have a csv file with a bunch of "empty cells" and a few missing values. I was able to impute the mean of the variable value to fill in the missing values. However, I'm unable to replace the empty cells with a certain text that I want to. I have been trying the same impute function to replace the empty cells but the output does not change. Appreciate any help. Thank you

Here's one way to replace empty strings in a data frame column col:

df$col[df$col == ""] <- "whatever you want to put there"
