[R] bootstrapping data.frame and matrix

[cp133]

Dear All,

When bootstrapping a statistics based on more than one vector, from a
data.frame or a matrix object, it looks like I am not able to pass the
data to R. What am I doing wrong?
I use the library "bootstrap".
Here is an example with a data.frame called "data"


 "boot2_bootstrap(data, theta, nboot)

I get the following error message:

Error in inherits(x, "data.frame") : Argument "xdata" is missing, with
no default"


Please note that the same is happening when I create a matrix from the
data.frame with the function cbind
(i.e.  
names(data)
[1] "shortrate" "y1"        "y5"        "y10"       "y15"      
"y20"      
[7] "y25"      
xdata_cbind(data$y10,data$shortrate)
is.matrix(x.data)
TRUE)

Thanks in advance,

Chiara
