Dear mates,
I am bit of stuck with a coding, all I have to do is to clean and tranform
the missing data "-999997" of the attribute "ej" into a normal number value
in a range from 0 to 22. My steps are :
1) first return the subsets, as check, they do sum to original
2) manipulate the attribute "ej" separately and replace them
# assuming you have done one round of cleaning now and saved the result in
a file called test.csv.
data<-read.csv("test.csv", header=T)
data1 <- subset(data, ej=="-999997")
summary(data1)
# ND now listed as an Other field
data2 <- subset(data, ej!="-999997")
summary(data2)
# can store the contents of ej and copy them back into data1 and data2.
# or just operate on them directly;
vector_with_ej <- data1$ej
vector_without_ej <- data2$ej
So, How to do next? can anyone please give me some comments? Many thanks!
