Dear all,
I have the problem, please, help me. I tried to import the dataset from the SPSS
into the R. It is the panel (survey). The importing of the data show that my
variables are read as afactor in R. But I need the variable "income" as a
numeric one. I tried to use the following command:
for(i in
c("AGE99","AGE00","I99PTOT","I00PTOT","I99PTOTN","I00PTOTN","I99PTOTG","I00PTOTG"))
+ {df[[i]]<-as.numeric(df[[i]])}
and then I get the error message. Error in "[[<-.data.frame"(*tmp*, i, value = as.numeric(df[[i]])) : replacement has 1 rows, data has 6335
What can I do? Could you please help me. I need it for my work.
Is df really a data.frame? Can you tell us about its structure using str(df)? What is your version of R?
Your statement works for me with a simple example of df[[i]].
