Re: [R] R ANOVA gives diferent results than SPSS

a one-way ANOVA should be a one-way ANOVA I guess, model is simple enough I thought. The F value seems pretty clear, I'm doing nothing fancy here, just trying to figure out how to do in R what I'm doing in SPSS. -- View this message in context:

[R] Dual Category X-Axis (Multi-Level)

Hello, I was wondering if anyone knows of a way to produce multilevel x-axis groupings similar to Excel's pivotcharts. (If you're not sure what I'm talking about, here's an example: http://peltiertech.com/WordPress/chart-with-a-dual-category-axis/). I realize that I could use mtext to

Re: [R] trouble with read.table and colClasses='raw'

The other possibility is that you could create the function to convert from character to raw (possibly wrapping as.raw around as.integer) so that read.table knows what to do. -- Gregory (Greg) L. Snow Ph.D. Statistical Data Center Intermountain Healthcare greg.s...@imail.org 801.408.8111

Thank you for your input so far r-help denizens. Neither David nor Peter were able to replicate my result. Has anybody other than me been able to generate the failure I'm describing? So far I've experienced it on 3 machines, Windows XP/P4/2.1.10, Windows XP/Atom/2.1.10/2.1.11(release), Windows

Re: [R] R ANOVA gives diferent results than SPSS

A couple of possibilities: The data is not the same, e.g. something in the file was interpreted differently by the 2 programs, one of the programs may have stopped reading at an unrecognized value, while the other skipped it and went on. Or it used to be common to encode missing values as

Re: [R] Find each time a value changes

It was brought to my attention that the rle() answer to this question was not posted. The following gives the correct answer once the last value is deleted. x-seq(1:100) y1-rep(1,10) y2-rep(2,10) y-c(y1,y2,y1,y1,y1,y2,y1,y2,y1,y2) xy-cbind(x,y) print(xy) print(str(xy)) # SEE WHAT RLE GIVES

Re: [R] Suprising behavior of paste or cat?

I don't think you have said how you are examining the output files. Is it possible that your text editor is assuming that the files are UCS-2 (Unicode), even though R is writing ASCII? Duncan Murdoch On 11/02/2010 1:44 PM, Russell Pierce wrote: Thank you for your input so far r-help

Using mtext is probably one of the most straight forward ways. You can also use something like: par(mfrow=c(1,3), mar=c(5.1,0,4.1,0), oma=c(0,4.1,0,1.1)) one - 1:3 two - 2:5 three - 6:4 names(one) - LETTERS[1:3] names(two) - letters[2:5] names(three) - state.abb[6:4] tmp.ylim -
