Subject: [Rd] bug report for as.function (PR#7702)
Message-ID: <20050224145913.A7774B275@slim.kubism.ku.dk>

Hi,

I got the following message in R:
Error in as.function.default(pdfs[1]) : invalid body argument for "function"
Should NEVER happen; please bug.report() [mkCLOSXP]

Operating System: Windows XP (SP2)
R version: R-2.0.1
Code causing error follows:

# create two probability density functions for mixtures of normal 
distibutions
fmix1 <- function(x) {dnorm(x, mean=4, sd=2) * 0.5 + dnorm(x, mean=7, 
sd=1) * 0.5}
fmix2 <- function(x) {dnorm(x, mean=3, sd=1) * 0.4 + dnorm(x, mean=6, 
sd=2) * 0.6}

# put them together
pdfs <- c(fmix1, fmix2)

# perhaps this is not as it was intended but it leads to the bug.report 
message
as.function(pdfs[1])

Meanwhile I solved this problem otherwise.
Hope this helps.
Timo
