R help - Oct 2007 - lm.boot function gives error

When I run this calculation

  library(ISwR)
  library(simple.boot)
  data(thuesen)
  fit <- lm(thuesen$short.velocity~thuesen$blood.glucose)
  summary(fit)
  fit.sb <- lm.boot(fit,R=1000,rows=F)
  summary(fit.sb)

I get the following error from the lm.boot routine:

  newdata' had 100 rows but variable(s) found have 24 rows

I don't know what this error means. Also, this example is not vastly
different than the one given in the simple.boot documentation and yet I
can't get it to run. Any suggestions? Thanks.

Tom

I'm too lazy to install the package, but does it not help if you write 
the model call as

lm(short.velocity~blood.glucose, data=thuesen)

?
