Problem with lm
But the 'y' is a parameter to the function, so does this mean that the error is occurring when the function is invoked without that parameter?

Yes, it is most likely due to scoping. It is safest to create a data frame with all the data in it, then pass that to the data argument of lm. On Thu, Nov 1, 2012 at 2:25 AM, Eva Prieto Castro <evapcastro at yahoo.es> wrote:
Hi,
I have a problem in relation with a packahe I made. It runs on my machine (Windows, where I made the package), and it runs in a Mac machine, but it does not run in another Mac machine with the same R version.
The part of the code is giving problems:
singleCosinor <- function(t, y, period=24) {
x1 <- cos(2 * pi * t / period)
x2 <- sin(2 * pi * t / period)
single <- lm (y ~ x1 + x2)
return(single)
}
The error:
Error en eval(expr, envir, enclos) : objeto 'y' no encontrado
Can it be in relation with scoping?.
Thanks in advance.
Eva
