In writing data out to a file, how to define the number of digits of data?
I would throw out the digits at the end when writing it to a text file.
Therefore, I look for usage on page format using write(), write.table().
In particular, options(digits=..) has no effect.
Example:
x <- matrix(1:100, 10, 10)
x <- log(1+x)
# x is a matrix of fractions with long digits.
write(x, "x")
# "x" is messy to read; not many digits of precision are necessary.
options(digits=3)
write(x, "x")
#no effect.
