as.numeric(as.character(DF$precip))
Hope this helps,

Hi R users,
I'm wondering why the values changed when I try to transform factors into
numerics.
For example, for a data frame DF, there is one column called precipitation,
which is usually lower than 100mm. But this column is factor when I read in
the data. When transform to numeric values, some rows can be higher than
1000mm. What is the problem? Thanks.
DF$prec_new = as.numeric(DF$precip)
