Thanks for your reply!
Sorry I did not clarify that I was using base64encode and base64decode
functions provide from "caTools" package. It seems that if I convert the
string to the raw type first, it still solves my problem.
My original problem actually is that I have a string:

Hi Jim,
Your example works perfectly. Any possibility that the sizing could be
automated. I am using bwplot. I can also use a prepanel function if needed.
Please find attached the code, data and output.

Hi Fayex,
Try this:
xdat<-data.frame(a=rnorm(100),b=rnor
There are a variety of ways to make box plots (e.g. base graphics, lattice, and
ggplot2). As the message footer says, you should be reading the Posting Guide
and providing a reproducible example (with sample data).

Hi Filippo,
I would advice you to use the RcppArmadillo package - maybe in combination with
the inline package. It is extremely fast and very flexible. A simple RNGScope()
lets you take the RNG from R. I myself programmed an MCMC sampler with this
package and it is much faster, than the one I h

That instance of 's' is a function and you were offering it (multiplied by 5)
as a data argument to the theta parameter of 'persp'. I can't intuit what your
reasoning might have been because you haven't explained why you thought that
would succeed.

Because that exposes the identically named functions and forces the
user to sort them out, inviting mistakes, especially when trying to
maintain/update them. My view is that one should try to program to
make code as robust and maintainable as possible. Nevertheless, as I
said, maybe this approach
look at the shiny package on CRAN.
it is from RStudio
