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.

Changing library(RODBC,boot) to library(RODBC) library(boot) seems to have solved the problem. _____ _____________________________________________ From: Gary Smith [mailto:[email protected]] Sent: Saturday, January 31, 2009 12:55 PM To: '[email protected]' 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 installedinstall.packages('boot')trying URL 'http://cran.stat.ucla.edu/bin/windows/contrib/2.8/boot_1.2-35.zip' Content type 'application/zip' length 779420 bytes (761 Kb) opened URL downloaded 761 Kb package 'boot' successfully unpacked and MD5 sums checked The downloaded packages are in C:\Documents and Settings\Gary Smith\Local Settings\Temp\RtmpRT1RUh\downloaded_packages updating HTML package descriptionslibrary(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))Error: could not find function "corr" 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.
