Hi list,

It seems that as.numeric is rounding up my numbers that are in a character
format.

Example:

a
[1] "776554.45" "776985.31" "776076.03"
"776092.01" "776151.42" "776276.97"


b <- as.numeric(a)
b
[1] 776554.4 776985.3 776076.0 776092.0 776151.4 776277.0



I've tried as.numeric(a,2) and as.numeric(a, digits = 2) but it didn't
work, nor  ? as.numeric gave me any clues. How can i transform my character
numbers in numeric without loosing the decimal digits?

Thanks,

Monica
