How to export data with defined decimal places

?write.table

which says, under details:

"In almost all cases the conversion of numeric quantities is governed
by the option "scipen" (see options), but with the internal equivalent
of digits=15. For finer control, use format to make a character
matrix/data frame, and call write.table on that. "

Not sure if this is what you want, as "export" is rather vague.

Hi all mailing listers,

I want to export data with specified precision into .txt file. How can I
make it? See  below

sprintf("%.10f",pi)
[1] "3.1415926536"

when carry out write.matrix(pi,"pi.txt"), 3.141592653589793115998 in pi.txt
file not with 10 decimal places like using sprintf("%.10f",pi)


Thanks

Marino
