barplot(height,width,xlim=c(-1,4), space=c(-.5,1.5,1.5))
will do the trick.
"space" is a relative parameter depending on "width" so you get
1.5*0.4=0.6 space and with width=0.4 you get an overall distance of 1

The ifelse function only apply to a single test passed as first
argument, and the second and third arguments are the value returned,
and thus should not be an R in
source'ing is a bad practice because this saves additional copies of
functions and data in the local workspace.
Wasting disk space is not a problem now since HDDs are cheap and function
bodies are generally small.
But, when you change any function body, you have to repeat that source()
call in l

Yes, you're right. Replacing :
<>=
ggplot(d,aes(y=t,x=u)) + geom_point(colour=alpha('black', 0.05))
@
with :
<>=
print(ggplot(d,aes(y=t,x=u))
Having your functions in a text file, say "functions.r" and then calling:
>source("functions.r")
is also an option. This assumes you are in the same directory as "
functions.r". Perhaps take a look at ?setwd and ?getwd as well.

I have a function like this:
changedir <- function(dataframe) {
dir <- dataframe$dir
gc_content <- dataframe$gc_content
d <- ifelse(dir == "-",
gc_content <- -gc_content,gc_content <- gc_content)
return(d)
}
The goal of this function is to be able to input a data frame like this:

Hi I'm simulating missing data patterns and I've started to get a lot of
functions in the same .R file is it possible to store al these functions in
a library like one does in C++ (i.e the .h file) and read the functions from
the main .R file
