R help - Aug 2011 - A small nag

Hi,

I am not sure how to fix the following error.

LGD <-  c(11.6,   12.3,      15.8,      33.1,      43.5,      51.3,
67.3,      84.9)

cor (x=(file [1:47231,3:10]), y= rep (LGD, 47231), method = "pearson")

Error in cor(x = (file[1:47231, 3:10]), y = rep(LGD, 47231), method
"pearson") :

  incompatible dimensions
> sessionInfo()

Thank you.

Hi Chintanu,

Do you want the correlation of columns 3:10 of file with the y vector
or do you want a correlation matrix of all variables?

## correlation between cols 3:10 and y
sapply(file[1:47231, 3:10], FUN = cor, y = rep(LGD, 47231), method =
"pearson")

## correlation matrix
cor(cbind(file[1:47231, 3:10], rep(LGD, 47231)), method = "pearson")

HTH,

Josh

I am new to R. Have a naive question about the boa package.
I loaded the package as instructed, and after entering
R > boa.menu()
I could never got the ready prompt (R hung).
>Can someone help? Thanks.
