[Rd] How to debug C code running in R

[Tong Wang]

Hi,
I am in the situation where I could get my code run correctly under GNU C, 
but it produced different (strange) results
while running in R . ( I use .C to call the function).   May I get some general 
advice on how could I do step by step debug
of source code in R ?

Thanks

[Rd] dput/dget when a data frame has 2 rows (PR#9627)

[pdmmac]

This doesn't seem right; I'm using R version 2.4.1 (2006-12-18) on Mac OS
and Win XP and find the same issue:

> mydataframe <- data.frame(ppi=c(.5,.5),mmu=c(5,10))
> dput(mydataframe,"mydataframe.txt")
> dget("mydataframe.txt")
Error in attributes(.Data) <- c(attributes(.Data), attrib) :
row names must be 'character' or 'integer', not 'double'
> mydataframe3 <- data.frame(ppi=c(.5,.5,.5),mmu=c(5,10,15))
> dput(mydataframe3,"mydataframe3.txt")
> dget("mydataframe3.txt")
  ppi mmu
1 0.5   5
2 0.5  10
3 0.5  15
