bwplot puts the bars in the wrong place
Dear R-Help,
With the attached data set, I am still getting incorrect bwplots
> xyplot(gdf$tt~gdf$OnHour |gdf$Runway, data=gdf) # Is correct
> bwplot(gdf$tt~gdf$OnHour |gdf$Runway, data=gdf, horizontal=FALSE) #
Puts the boxes on the wrong x-axis values
# look especially at 0 and 3. How do I fix this?
What is happening?
Thanks,
Jim Rome

How to select a row from one dataframe that is "close" to a row in another dataframe
I have two data frames of flight data, but they have very different
numbers of rows. They come from different sources, so the data are not
identical.

[1] "FltOrigDt" "MkdCrrCd"
[3] "MkdFltNbr" "DprtTrpnStnCd"

How to use tapply for quantile
I am trying to calculate quantiles of a data frame column split up by
two factors:
# Calculate the quantiles
quarts = tapply(gdf$tt, list(gdf$Runway, gdf$OnHour), FUN=quantile,
na.rm = TRUE)
This does not work:
> quarts

ggplot2 and facet
I have a data frame (attached) that has interpolated EOT errors for
each minute before flight landing. It also has the runway and an index
for the flight:

How to suppress factor labels
I am using ggplot2 to make a boxplot that overlays a scatterplot:

Comparing dates in dataframes

the weather is good. arr has a Date and quarter hour column.

How to speed up interpolation
df is a very large data frame with arrival estimates for many flights
(DF$flightfact) at random times (df$PredTime). The error of the estimate
is df$dt.
My problem is that I want to know the prediction error at each minute
before landing. This code works, but is very slow, and dominates
everything. I tried using split(), but that rapidly ate up my 12 GB of
memory. So, is there a better R way of

Kronecker matrix product
Hi
I want to write a little function that takes a matrix X of size
m-by-n, and a list L of length "m", whose elements are matrices all
of which have
the same number of columns but possibly a different number of rows.
I then want to get a sort of dumbed-down kronecker product in which
X[i,j] is replaced by X[i,j]*L[[j]]
where L[[j]] is the j-th of the "m" matrices. For

Bug in Sweave? -- scoping problem? (PR#8615)
I have found a strange scoping problem in Sweave. The following Rnw
file doesn't produce the same output in Sweave as it does if I produce
an R file using Stangle and execute that:

extracting rows of a dataframe
Hi
look at the following session, in which I have a dataframe,
and I want to extract the second row, without the first column.
Everything works as expected until the last line, where I set
the names of x to NULL, and get a non-desired object (I
want c(4,3).).
Three questions:
(1) why is as.vector(a[2,-1]) not a vector?
(2) How come setting names to NULL gives me bad weirdness?
(3) Can I

Call to rgamma using .C causes R to hang

I've been trying to get this working for ages, but it causes R to hang.

result[0] = rgamma(*x, 2.0);

Internal codes of the factor
Hello!
I am writing some functions and I repeatedly acces internal factor
codes. I figured out that internal codes are 1:n where 1 represents 1st
level, 2 2nd level etc. This is not documented and I wonder if this is
on purpose and subject to change or would be a good idea to add this to
documentation for factor? I can prepair a pacth if this is accepted.

bounding box in PostScript
When a graph is saved as PostScript, the bounding box is often too big.
A consequence is that when the graph is included in a LaTeX document,
the spacing does not look good.
Is this a recognized problem? Is someone working on it? Could I help?

how to specify dev.print target by a variable?

How do I do this such that I can specify FOO to be one of several choices? (GDD, PNG, postscript, etc.)
If I make FOO a character variable, then "dev.print" complains.
