Hi, R people.
In ?factor, in the "Examples:" section, we see:
## suppose you want "NA" as a level, and to allowing missing values.
(x <- factor(c(1, 2, "NA"), exclude = ""))
is.na(x)[2] <- TRUE
x # [1] 1 NA, used because NA is a level.
is.na(x)
# [1] FALSE TRUE FALSE
I'm a bit

Hi,
is there a (cross-platform) file-locking mechanism available in R (or
via some package)?
I am looking for a way to have one R session lock a file for
read/write access, while being updated/modified by another R session.
This will provide me with a-poor-mans parallelization method. It is

In my version at the time, bxp did not list which plot parameters it does not
accept. xlim was simply not mentioned at all. I can't easily see lack of a

Thanks for this. So at the risk of treading out too deep into unfamiliar
water, one concern is that if I run 'lm' within a function and then the
function exits, am I still (perhaps unnecessarily) keeping a copy of the
function environment and the associated data? It does not seem that

Note that ?bxp quite carefully says which graphical pars it does and does

a bug.
The easy part is to allow it to accept 'xlim' is specified. The harder
part is to find a good default of xlim in general. Steve's suggesti
If anyone in R-devel is having trouble seeing the point of this, try
this little example with the new code of Brian's:
dat <- data.frame(x1=1:20, x2 = sample(1:20), y = rnorm(20)+1:20)
fm <- lm(y ~ x1+x2, dat)
par(mfrow = c(2,2))

Yes, that was the intention (to go into R-devel).

Precisely. Thanks Brian.
I did do something like this but not nearly so elegantly.
I suggest this become the standard version in the next release. I can't
see that it can break any existing code. It's a pity now we can't make
ylim = "common" the default.

Is the attached the sort of thing you are looking for?
It allows ylim to be specified, including as "common".

Does anyone have, or has anyone ever considered making, a version of
'termplot' that allows the user to specify that all plots should have
the same y-limits?
This seems a natural thing to ask for, as the plots share a y-scale. If
you don't have the same y-axes you can easily misread the comparati
