Hi all,
I am generally quite fond of the unix commandline keystrokes (e.g. searching
back in your history with [CTRL]-R, and cutting/pasting with [CTRL]-K/Y)
which work in the R commandline in *nix. Does anyone know if there's any
way to get similar functionality in the Windows RGUI?
I know tha
sounds great. there are often times I'd like to use reshape on data frames
of hundreds of thousands or millions of rows, but I have found that it is
just too slow at this point to be convenient.
thanks again for everything,
Mike

time, mean,
margins="diet")$diet) #returns TRUE
does that make sense? the way it works now, it totally screws things up
when the column for which you get margins is not a factor. in my case, a
date column.
thanks,

according to the documentation of the cast function in the reshape function,
I would expect this bit of code from the examples to calculate marginal
means over only the 'diet' variable.
#Chick weight example
names(ChickWeight) <- tolower(names(ChickWeight))
chick_m <- melt(ChickWeight, id=2:4,
try this:
scores.melt = data.frame(grade = floor(runif(100, 1,10)), variable =
'score', value = rnorm(100));
cast(scores.melt, grade ~ variable, fun.aggregate = c(mean, length))
it has the nice column names of:
grade score_mean score_length
1 1 0.087885358
2 2 0.16720
I'm running into some problems with the spacing of some faceted ggplot plots.
I have a number of time series faceted to be one above another, but the
scale labels of the y axes all clobber each other at the bottom/top of each.
for example, try:
qplot(x, y, data = data.frame(x = 1:10, y = 1:10,
Dear all,
With normal plotting, one can size a set of points in a plot using a vector
argument to cex in the points() function. This works whether you are using
one of the standard R symbols (i.e. 19+) or some ascii symbol, such as '/'
eg:
plot(1:10, 1:10, type='n');
points(1:10, 1:10, cex = 1
hey all,
I feel like I must be missing something rather plain, but I don't get it.
how is one supposed to use R as a PgSQL client on Windows? Assume my
windows desktop is on the same network as a PgSQL server, and I just need to
use R to connect and pull down some data.
