solving equations
You could try using 'uniroot':
f <- function(F) { F - (25*(F+0.2)/22.2/(exp(F+0.2)-1)) }
uniroot(f, c(0, 1))$root

Dear R-users, I'm trying to solve the following equation: F=25*(F+0.2)/22.2/(EXP(F+0.2)-1) In Excel I found F=0.696176718 but I'd like to know how to use R to solve it. I tried, without success, to use "solve".
