Hi, You need to use as.numeric on the column, not the entire data frame.

You showed us str(cmie.dts), but then tried to do something with f. But assuming they're similar, see: fakedata - data.frame(col1 = c(100.01, 20.01, 30.05), stringsAsFactors=FALSE) str(fakedata) 'data.frame':3 obs. of 1 variable: $ col1: chr 100.01 20.01 30.05 as.numeric(fakedata) Error: (list) object cannot be coerced to type 'double' as.numeric(fakedata$col1) [1] 100.01 20.01 30.05 -- Sarah Goslee http://www.functionaldiversity.org __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Hello, It's the column that you want to convert, not the data.frame. f1 - as.numeric(f$INE001A01036) Hope this helps, Rui Barradas Em 07-12-2012 14:23, Vikram Bahure escreveu: Dear R users, I am facing a pretty a unusual problem while converting character to numeric.

Re: [R] Converting character to numeric: Error: (list) object cannot be coerced to type 'double'
Thanks a lot. That was helpful. My apologize, as both cmie.dts and 'f are same.
