Dear group,

Here is my data frame:

position100415 <-
structure(list(DESCRIPTION = structure(1:9, .Label = c(" SUGAR NO.11 Jul/10
", 
" SUGAR NO.11 May/10 ", "CORN May/10 ", "COTTON NO.2 Jul/10 ", 
"CRUDE OIL miNY May/10 ", "ROBUSTA COFFEE (10) Jul/10 ", "SILVER May/10 ", 
"SOYBEANS Jul/10 ", "WHEAT May/10 "), class = "factor"), POSITION = c(3, 
-1, 3, 4, 3, 10, 1, 1, 6), SETTLEMENT = c(17.08, 16.85, 363.25, 
82.12, 85.51, 1386, 1843.3, 993, 480.25)), .Names = c("DESCRIPTION", 
"POSITION", "SETTLEMENT"), row.names = c(NA, 9L), class = "data.frame")

As you can see, I have a blank at the end of each name of objects of list
DESCRIPTION (e.g "COTTON NO.2 Jul/10_",. I need to remove them.
My data frame has been obtained from a .csv file and then a few command
lines.
Here is the first line of my code :

pose=read.csv2("LSCPos100415.csv",sep=",",dec=".",as.is=T,h=T,skip=1)[,c(4,8
,14,15)]

As you can see, the blank already exists (e.g "CORN May/10_"), so it should
come from the Excel file itself. 

pose <-
structure(list(DESCRIPTION = c("CORN May/10 ", "CORN May/10 ", 
"SOYBEANS Jul/10 ", "WHEAT May/10 ", "WHEAT May/10 ", "WHEAT May/10 ",

As I can't change anything on the Excel side, how can I remove these blanks
on the R side??

TY for help.
