Perfect. In conjunction with Jorge's contrib that works a treat. Thanks. Dan On Tue, 2009-03-24 at 19:00 -0400, David Winsemius wrote: > ?try > ?tryCatch

how to plot mean+/-SD from externally calculated values
Dan Kortschak · Nov 19, 2009 · r-help

Thank you for that, you have helped amazingly.Are you also able to point me to a barplot equivalent? Dan On Thu, 2009-11-19 at 18:53 -0500, David Winsemius wrote: > > install.packages("plotrix") > > library(plotrix) > > ?plotCI >

some questions about R internal SEXP types
Dan Kortschak · Sep 8, 2020 · r-devel

I was not. I was explaining why my expectations exist. I honestly surprised that this would be misinterpreted. Dan On Tue, 2020-09-08 at 13:47 +0200, Tomas Kalibera wrote: > Please don't use this list for advertising on...

how to plot mean+/-SD from externally calculated values
Dan Kortschak · Nov 19, 2009 · r-help

Hi, I am trying to plot a set of means+/-SD calculated by an external program (an RDBMS) since the data set is too large to happily fit in R (740M x 100 values - which are summarised to 100 means...

source definition for R_NilValue/return from TYPEOF(R_NilValue)
Dan Kortschak · Dec 15, 2019 · r-devel

Hello, for reasons I want to know the return value of TYPEOF(R_NilValue), I expect it to be NILSXP, but I can't find this documented anywhere. Ideally, I'd like to see the source definition of R_NilValue...

multiple paired t-tests
Dan Kortschak · Mar 24, 2009 · r-help

Hi R users, I have a very large data set that has two conditioning variables for the test I want to perform. A toy set can be simulated: type<-sample(1:3,100,replace=TRUE) class<-sample(1:20,100...

multiple paired t-tests
Dan Kortschak · Mar 24, 2009 · r-help

That is a valid point, the number of samples I expect to be different is actually quite small, but it is supportable (or otherwise) by other experimental data. Unfortunately the question I really want answered is pretty much covered by...

some questions about R internal SEXP types
Dan Kortschak · Sep 8, 2020 · r-devel

Thanks, Alex. That might be good enough for me for this particular concern; in the absence of a language specification specifying my behaviour and referring to precedent seems like a reasonable fall back. Dan On Tue, 2020-09-08 at...

how to plot mean+/-SD from externally calculated values
Dan Kortschak · Nov 19, 2009 · r-help

I appreciate the frank comments; I did try the examples on the help page, but as someone new to R programming (it still makes my head hurt) I missed the barplot example (I noticed it but assumed - now I know...

some questions about R internal SEXP types

Thank you everyone who has helped a non-R developer attempt to build a tool to extend the R ecosystem. >From what I've read, it looks like I should document the sexp internals package I provide as a here...

changing number of axis
Dan Kortschak · Oct 1, 2009 · r-help

Thanks for that again. That almost works, except that lines are drawn between non-empty bins (in various degrees of diagonality), so absent points (important here) don't show clearly. It's not a huge issue, so I might leave...

changing number of axis
Dan Kortschak · Sep 16, 2009 · r-help

Hi, I trying to produce a bar chart describing hits to specific bins by chromosome for a large data set (I am asking here because experimentation with options is precluded due to this - generating the figure takes about an hour...

lattice multipanel strip placement - with two factors
Dan Kortschak · Mar 23, 2009 · r-help

That's part way to my desired solution, but not completely there. Here's an example: chromosome<-rep(c("A","X","Y"),time=20) type<-rep(c(1:20),times=3) length<-rnorm(60) densityplot(~length | type * chromosome, layout=c...

changing order of lattice plots
Dan Kortschak · Mar 23, 2009 · r-help

Hi, This is another question relating to my 2 factor figure. densityplot(~End-Begin | Type * Chromosome, data=Mon, layout=c(5,12), xlab="Element Length",type="percent", col="grey60", strip=strip.custom(style=3, bg="grey90", par.strip.text=list...

lattice multipanel strip placement - with two factors
Dan Kortschak · Mar 22, 2009 · r-help

Hi, I'm making a multipanel lattice densityplot figure with 2 factors (3 and 20 classes in each factor) with the following statement (the type="percent" is there to prevent plotting the actual points which detract from the figure - is...

how to prevent lattic barchart from drawing bar completely to the bottom/left of the chart
Dan Kortschak · Nov 22, 2009 · r-help

Hello, I am trying to use lattice barchart so that it will draw a barplot where the bars do no reach the frame of the chart, but only extend to 0 as the minimum. With barplot, I can set this...
