can't get package boot to load

Changing 
library(RODBC,boot)
to
	library(RODBC)
	library(boot)
seems to have solved the problem.

Subject: can't get package boot to load

Hi,
I am new to R and I'm totally confused by this problem.  I'm trying to load
data and run a simple correlation using corr() in the boot package.
Yesterday my code worked.  Today it can't find the function corr().  I've
tried searching the web and haven't found the root of my problem.  Apologies
if I've missed the obvious.
My code is simple:

install.packages('RODBC')
install.packages('boot')
library(RODBC,boot)
setwd("C:/Documents and Settings/Gary Smith/My Documents/Blog/")
data = odbcConnectExcel("LafferCurve2.xls")
mydata = sqlFetch(data,"Data")
n=23
m=73
gnp=mydata[[3]][n:m]
incTaxFirst=mydata[[7]][n:m]
corr(cbind(gnp,incTax))

Here are the console messages:

> install.packages('RODBC')
Warning: package 'RODBC' is in use and will not be installed

Using search(), I see:
[1] ".GlobalEnv"        "package:RODBC"    
 [3] "package:stats"     "package:graphics" 
 [5] "package:grDevices" "package:utils"    
 [7] "package:datasets"  "package:methods"  
 [9] "Autoloads"         "package:base"     

Typing "install.packages('boot')" at the prompt gets me the same result.

Thanks for any help.

If you check ?library, you will see that the package argument only takes one
packages. So your code was like saying library(package=RODBC, help=boot)
which does not make sense...but which would indeed load RODBC and not boot.
That is why your problem occurred and why your solution worked.
