Results of applying na.omit on zoo object
I read in ?na.omit that it returns the object with incomplete cases removed. I interpret this to mean that any zoo object row where any column shows 'NA' will be removed from the data set. That's not what I need, since the 'NA' represents information in my context. However, what I would like to do is eliminate the rows where every column is 'NA'. When I aggregate

Controlling Order of Panels in Lattice Trellis Plots
With multiple panels in a lattice trellis plot the sequence is, for example, 1, 10, 11, 12, 2, 3, 4. I want the sequence to be 1, 2, 3, 4, 10, 11, 12. Reading ?strip.default and the appropriate section in the Lattice book I'm not seeing how to specify the 'human' numeric order rather than the computer numeric order. A pointer will be appreciated. TIA, Rich

optmizing with monotone stepfunctions?
Before re-inventing the wheel I would like to ask: does anyone know about an optimizer in R which can reliably identify which value of X (Xopt) leads to Y (Yopt) closest to Ytarget in Y <- MonotoneStepFun(X) optionally with the restriction that Yopt <= Ytarget (at least if any Y <= Ytarget, otherwise any Yopt > Ytarget would be the preferred answer) If none is known, I will write

read.table() Issue
Yesterday I changed the headers for a couple of columns in data text files and removed hyphens from within character strings, too. When I tried to re-read these data sources using read.table() I encountered an issue I've not before seen. Both files were read almost instantly until yesterday's wording changes. Now both files seem to cause R to hang. Rather than having the prompt

Changing data frame column headings
I have a reshaped data frame with value column headings concatenated from two column headings in the melted data frame. I want to change all 56 headings in a single command, but 'names' allows me to change only one at a time. In Hadley's 2007 article on reshape in the Journal of Statistical Software he mentions a 'rename' function, but I cannot find that. Is there a way to

Modifying Package Data
The bio.infer package contains a data frame /usr/lib/R/library/bio.infer/data/itis.ttable.rda that needs to be modified. After loading the bio.infer package and attaching the data frame with the data() function, I wrote the data frame to a text file. After adding another row to the data frame I applied read.table() to create a data frame, but it's in my pwd, not the R library data

reshape2's dcast() Adds NAs to Data Frame
I need to understand how and why dcast() adds NAs to a data frame that contained no missing values. The database table of chemical concentrations has all missing values removed because they cannot contribute to data analyses. The structure of the R data frame of these data have no NA values, and neither does the data frame resulting from applying the reshape2 melt() function to it. However,

limit to p-value using t.test()
Hello, I am using t-test to check if the difference between two poulations is significant. I have a large N=20,000, 10,000 in each population. I compare a few different poulations with eachother and though I get different t-scores, I get the same p-value of 10^-16 which seems like the limit for this function. Is this true and is so, is there a workarounf to get a more sensitive/accurate p-value?

Entering Multiline Commands With ESS
If there's a separate ESS user mail list, please point me to it. I'm using emacs with ESS and want to enter multiline commands for plots. Examples in my reference books show each line terminating with a comma so labels and other attributes can be specified for the plot before it is submitted for rendering. When I try to do this, however, I get an error: > boxplot(chemdata$quant ~

Installation test fails: 2.04b
...a-2.04b was installed from the rpm. I'm using Carter and Sharpe's "Teach Yourself Samba in 24 Hours" as my guide.

Lattice: Understanding How Points Connected by Lines
A data frame has one factor, one date, and one numeric column. When I plot these using the default pch of the open circle (first attachment), xyplot(TDS ~ sampdate | she.s, data = sheep.cast, main = 'TDS in Sheep Creek', ylab = 'Concentration (mg/L)', xlab = 'Time') I see the higher concentration points toward the right on several panels. But, when I change to using a
