I have a dataset named malt, where one of the columns is named ka. I want to replace NA values in that ka column by mean values in malt$ka and other value remain as it is, so do this by if else 

 malt$ka <- ifelse(malt$ka=="NA", mean(malt$ka), "malt$AcqCostPercust")

This does not seem to work, and I am confused how to replace values the NA values.

Or

malt$ka[is.na(malt$ka)] <- mean(malt$ka, na.rm = TRUE)

x <- mean(malt$ka, na.rm=T) # assign mean value to a variable x
malt$ka<-ifelse(is.na(malt$ka),x,malt$ka)
