Dear people
I've learnt that by using the "boxplot.stats" command in the "grDevices" library
I can get the 5-number summaries of a boxplot, plus other important information,
like the confidence interval around the median.
I'm interested in knowing the actual formula to used in that package to

a friend and I are trying to develop a modest workflow for the problem
of decomposing tests of higher-order terms into interpretable sets of

is significant, it ma

to use qplot in Sweave and have you been successful? Any help woul

Exactly how is the translation of "X9-" -> 00911 done? Are there
unique mappings of character sequences to numbers? How many different
ones might there be? Why do you have leading zeros on the result?
If they are changed to numeric, then the default printing results in
'911'. Can you provide a

This may be a begining question. If so, please bear with me.

You're right, the problem was with the print function not displaying enough

I think you will find that the 'catastrophic loss of significance' is in
the printing at the default level. Try print(x, digits=15).

If you are using zoo for this you can do:
library(zoo)
set.seed(1)
x <- zoo(rnorm(7), as.numeric(1:7))
y <- zoo(rnorm(4), c(1, 2, 6, 7))
xy <- merge(x,y)
xy$y - xy$x
# or if you just want the difference at times existing in both
y - x
