It's not being rounded, as this example will show:
[1] 0.1234568x <- 0.1234567898765 x
print(x,digits=15)
[1] 0.1234567898765
It is being printed, or displayed, with fewer digits. But the underlying value has not changed.

Hi all R-users,
If I have a matrix with numeric elements as follows, the values are rounded when I try to refer to a specifici element using [], the value is rounded.
The same thing happens if the matrix is read from a file, the values are stored to the correct precision but then when I try to refer to a specific element (such as using [], it is rounded.
How do I avoid this rounding?
