[R] Replacing NA s with the average

[PIKAL Petr]

Hi.

sometimes is worth to try google first

R fill NA with average

resulted in

https://stackoverflow.com/questions/25835643/replace-missing-values-with-col
umn-mean

and from that

library(zoo)
na.aggregate(DF)

will replace all numeric NA values with column averages.

Cheers
Petr
