Dear Arup,
It's very difficult to know what's going on without more information. What
is the form of the data that you're importing and how are you reading the
data? I ask because the most common way of getting data into R is probably
via read.table(), which by default converts character data to f
There is an issue that is being overlooked here.
The read.table() family of functions use type.convert() by default
internally to determine the resultant data types of the columns going
into the data frame from the source text file. Everything read in by
read.table() starts as character and then t
if you use read.table for the import, reading about the colClasses
parameter in ?read.table may help.

You might want to try as.numeric(X), if you want to convert a factor then
you could use as.numeric(as.character(X)), where X is a "variable".
