Dear R-Helpers,
I have the following data set(y):
Test_Result #_Test
t 10
f 14
f 25
f NA
f 40
t 45
t 44
<NA> 47
t NA
I want to replace the NA values with the following method:
- for the numeric variable, replace NA with median
- for character variable , replace NA with the most frequent level
If i use x<-na.roughfix(y) the NA values are correctly replaced.
But if i x<-na.roughfix(y$Test_Result) i obtain the following error:
roughfix can only deal with numeric data.
How can i solve this proble that i met every time i want to replace only the
NA values of a column (type character)?
Thank you in advance.
