R help - Apr 2008 - 3 questions: debug R script, multi-level sorts, and multi-gsub

Hi,

1) I ran a script say test.R. It ran and terminated with an error. However,
I am not sure where the error occur.
> source("test.R")
Loading required package: tools

Welcome to Bioconductor

  Vignettes contain introductory material. To view, type
  'openVignette()'. To cite Bioconductor, see
  'citation("Biobase")' and for packages
'citation(pkgname)'.
Error: subscript out of bounds
2) I have looked deeply into R, but can't fine multi-level sorts.

3) I have a vector of words, several of which need to be replaced by
different unique words. I am using multi-lines of gsub, is there any elegant
alternative ?

When it stops with the error you can issue a

traceback()

command or run the script with echo=TRUE:

source("test.R", echo = TRUE, max = 1000)

At the top of the help page for sort...

"Sort (or order) a vector or factor (partially) into ascending (or 
descending) order. For ordering along more than one variable, e.g., for 
sorting data frames, see _order_. "

In the examples on the order page, it shows what I suspect you mean by 
a multilevel sort (although you offer no examples).
> (ii <- order(x <- c(1,1,3:1,1:4,3), y <- c(9,9:1), z
<-c(2,1:9)))
 [1]  6  5  2  1  7  4 10  8  3  9
> dd <- transform(data.frame(x,y,z),
+                 z = factor(z, labels=LETTERS[9:1]))
> dd
   x y z
1  1 9 H
2  1 9 I
3  3 8 H
4  2 7 G
5  1 6 F
6  1 5 E
7  2 4 D
8  3 3 C
9  4 2 B
10 3 1 A
> dd[ order(x, -y, z) ,]
   x y z
2  1 9 I
1  1 9 H
5  1 6 F
6  1 5 E
4  2 7 G
7  2 4 D
3  3 8 H
8  3 3 C
10 3 1 A
9  4 2 B
