Hi Walter,
To make sure that the current R working directory is what you think it is:
getwd()
If it is not what you want, you can change it with:
setwd("C:/Program Files/R/R-3.2.3/Appendix")
Notice that I have changed the backslashes (\) to slashes (/). You can also
use doubled backslashes if y

Ben,
Your solution solved my issue. Thank you. I do not see a need for a
nested function. Based upon your solution, I came up with
this solution:
fbob = function (...)
{
l1 = list(...)
for( i in 1:length(l1) )
cat( "i is ", l1[[i]], "\n" )
return (0);
}
It does not use nes

Hi,
Using the full path specification, as you have done in your second example, is
a good idea. Have you tried forward slashes? If I am reading the docs
correctly you should be able to use either forward or back slashes. I haven't
used R in Windows for ages, but my memory is that switching
Hi Walter,
I'm not sure changing the shortcut properties are the best approach.
Instead, after you start R, you can use the
getwd()
command to see where R will start looking for things, and the
setwd()
command to change that (wd is working directory).
Because of the way R parses strings, you eith

Hello everyone!
I'm sure this is very simple and that I'm just having "forest and trees"
syndrome.
I have the following character array:

I want to end up with

I've tried paste, paste0, gsub, no good.
Any suggestions much appreciated.

Looks like the data frame needs to be reshaped before being given to
ggplot.
"melt" function from the "reshape2" package, or "gather" function from
"tidyr" package are good tools for this.

Hi Stefano,
you try to facet on 'variable' and 'scales' which aren't part of your
data.frame as far as I can see. The error 'At least one layer must contain
all variables used for facetting' also tells you this - that at least one
of the variables you use for facetting are missing.
Hope this help

Thank you very much for all of the help!!! For what I need, Jim's and
Jeff's solutions were the most useful, but I really appreciate all of the

Now, I am trying to evaluate the performance of the model across time. So
as to do that I use rolling window which I understand as sort of a "leave

The example:
