Double x grid in ggplot2
I am trying to overlay raw data with a boxplot as follows:

xlab="Time before ON (min)", alpha=I(1/10),
ylim=c(-30,40), geom="jitter") +

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 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.

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,

ggplot seq
Hi Hadley: Not sure if you received my email, so I am resending it again.
I have dealt with this before and I can't remember how it got resolved. It is too much data to reproduce the example below(49.000 records) but all I am after is trying to get the x axis breaks. I want my x axis to go from 27 to 51 and 1 to 25 by 2. I am trying to concatenate the breaks but it sorts the seq() in ascending

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

Order of factors with facets in ggplot2
Hello,
I'd like to produce a ggplot where the order of factors within facets is
based on the average of another variable.
Here's a reproducible example. My problem is that the factors are ordered
similarly in both facets. I would like to have, within each facet of `f1',
boxplots for 'x' within each factor `f2', where the boxplots are ordered
based on the average of x

boxplots of various levels
noob here
trying to make boxplots of some data
i would like to separate the boxplots according to conditons of various

condition A,B,C,D
side: left and right

I would like separate boxplots of the results (x) of the tests (numeric) for
each group under each condition on each side over time.
