A simple question, but I can't find something to do what I want:
Given: a vector of numbers, like
lambda - c(0, 0.005, 0.01, 0.02, 0.04, 0.08)
Desired: format them in minimal space for use as plot labels, ie,
without leading or tailing 0s. For this example:
lambdaf - c(0, .005, .01, .02,
Here's one way to get rid of leading zeros before the
decimal point:
gsub(^0\\., \\., as.character(lambda))
[1] 0.005 .01 .02 .04 .08

Omitting the leading zero is dangerous, since the decimal point can disappear
in a poor hardcopy leading to later misinterpretation.
