R help - Sep 2009 - Suppressing script commands in R console when executing long program

Hi R users,


I have a script composing of more than 1000 lines and would like suppress
the R codes from the console when executing the script (to reduce the
physical processing time)

I have tried options(echo=T) but no luck..

*Q1. Are there any way of suppressing the commands in the R console?*

Also, when importing spreadsheet consisting of numbers with 1,000 separator
commas (i.e 10000 as 10,000) into R  and performing basic arithmetic, R does
not seem to recognise these separators..

*Q2. Is R capable of reading numbers that are represented with 1,000
separator commas?*
**
Many thanks for your expertise in resolving these problems.

You can try putting this in your Rprofile
options("keep.source=F")

This will work in the R cmd but it will not work in the RGui

Goodluck! :-)

I think this has been answered already.

I am not aware of an option to read.table and freinds that does this
but you can recover easily:
> foo <- read.delim('foo.tbl')
> foo
  A          B
1 1     12,300
2 2 256,001.01
3 3      900.1
4 4         80
> str(foo)
'data.frame':   4 obs. of  2 variables:
 $ A: int  1 2 3 4
 $ B: Factor w/ 4 levels "12,300","256,001.01",..: 1 2 4
3
> foo$B <- as.numeric(sub(',', '', as.character(foo$B)))
> foo
  A        B
1 1  12300.0
2 2 256001.0
3 3    900.1
4 4     80.0
> str(foo)
'data.frame':   4 obs. of  2 variables:
 $ A: int  1 2 3 4
 $ B: num  12300 256001 900 80
