I am new to R, and I need to do some simple data cleaning.
In the example below I have 164 rows of data with a missing value. I want to
convert these missing to unknown while keeping the other values as is.
summary(ABIClinical$HasSkinBreakdown)
no unknown yes
164 914 163 178
When I did the following code:
ABIClinical$HasSkinBreakdown<-ifelse(ABIClinical$HasSkinBreakdown=='',"unknown",ABIClinical$HasSkinBreakdown)
I get the following:
summary(ABIClinical$HasSkinBreakdown)
Length Class Mode
1419 character character
How do I get results as in my first statement,but with the missing values
converted to "unknown"?
