[R] as(, "numeric") vs as.numeric()

Hi everyone, Could someone please explain this R behavior to me: > typeof(as.numeric(1:10)) [1] "double" > typeof(as(1:10, "numeric")) [1] "integer" I expected "double" in both cases. In the help for the "as" function it says: "Methods are pre-defined for coercing any object to one of the basi

[R] .Call function crashes initializing matrix

Hello, I have a C function that I call from R using .Call. I recently discovered a bug in my code, and I am not sure if it is a problem with what I am doing in C or if it has something to do with my use of .Call. I have narrowed my problem down to these two C statements: int size = 5000; doubl

[R] Rprintf not updating

Hello all, I am using Rprintf in a C for loop (from .Call) to print a progress indicator showing the current percent complete. The loop I am doing is an time intensive call to another function. I have noticed that Rprintf does not print to the R-window until the entire loop has been completed.
