Thanks -Don
Details:
signif() rounds a number to a specified number of significant digits, for example:
x <- c(2.503,2.477,0.1204)
signif(x[1],3)[1] 2.5
signif(x[2],3)[1] 2.48
signif(x[3],3)[1] 0.12
All of these are correct, numerically. But, the trailing zeros do not display, naturally, because the R functions that format numbers for printing have no way of knowing that trailing zeros are desired. Pretending I have the function I need, named "fmt.signif", it would do this:
fmt.signif(x[1],3)[1] "2.50"
fmt.signif(x[2],3)[1] "2.48"
fmt.signif(x[3],3)[1] "0.120"
[1] "2.50" "2.48" "0.120"
signif(x,3)
For now, at least, I'm willing to assume that I never want the numbers formatted with exponential notation.
