HI all, I have a data frame with three variables. Some of the variables do have missing values and I want to replace those missing values (1represented by NA) with the mean value of that variable. In this sample data, variable z and y do have missing values. The mean value of y and z are152. 25 and 359.5, respectively . I want replace those missing values by the respective mean value ( rounded to the nearest whole number).
DF1 <- read.table(header=TRUE, text='ID1 x y z 1 25 122 352 2 30 135 376 3 40 NA 350 4 26 157 NA 5 60 195 360') mean x= 36.2 mean y=152.25 mean z= 359.5 output ID1 x y z 1 25 122 352 2 30 135 376 3 40 152 350 4 26 157 360 5 60 195 360 Thank you in advance ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
