It seems you are trying to check this via the following ?

edit() has been having problems with large files, however only
with more than 65535 rows.
HOWEVER, using edit() after read.table() to check your data is
not very recommended.
Use dim(mydata)
str(mydata)
and possibly also
names(mydata)
summary(mydata)
to check if the data frame was okay *before* you edited it,
using edit().
