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> install.packages('boot')

> 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.
Thanks for any help.
Gary
