if the titlebar could help to understand which is which.

Re: [R] Execute function at startup
I think you can already do this via .First(). If you start your .First with something like this [give or take some parentheses]
if( !is.null( runfirst <- Sys.getenv( 'RUNFIRST')))
try( eval( parse( text=runfirst))))
then whatever you pass in as RUNFIRST=... should get executed on startup. Could even be a call to source(...) if you want to source a particular file. I have a similar

New unique name
In some languages there is a function
gensym()
which returns a new unique name (in the current environment).
This is quite helpful when one has to do temporary assignments.
I could not find such a function in R.
Is there one?

histogram question
hist(rbinom(1000,10,0.5),col=2,xlim=c(0,10),ylim=c(0,300))
gives a histogram with "touching bars"
hist(rbinom(100000,10,0.5),col=2,xlim=c(0,10),ylim=c(0,30000))
gives a histogram with space between the bars.
is there a way to control the space betweent he bars easily?

factor always have type integer
typeof applied to a factor always seems to return "integer",
independently of the type of the levels.
This has a strange side effect.
When a variable is "imported" into a data frame,
its type changes.
character variables automatically are converted
to factors when imported into data frames.
Here is an example:
