bug in subs()

[stla]

Hello,

I think that subs() does not correctly work:

options(symbols = c("a","b","A","B"))
g <- inverse(alpha(1)) + alpha(2) # a^-1.b
subs(g, inverse(alpha(1)), alpha(3)) # should be A.b
# result: A^-1.b

Hi there, thanks for this, not sure why I didn't see this comment until just now. Function subs() works on symbols, not semantic meaning which is why the idiom you post looks plausible but doesn't work as expected. I'll add some clarifying text to subs.Rd in a minute. Best wishes
