The example below creates parallel time-series plots of three different y variables conditioned by a dichotomous factor. In the graphical layout, ? Each y variable inhabits its own row and is plotted on its own distinct scale. ? Each level of the factor has its own column, but within each row the scale is held constant across columns. ? The panels fit tightly (as they do

Within a function I'd often like to obtain a text string equal to the name of the function. One use for this: To generate a filename for use in pdf(). This enables me to keep track of which function generated a particular graphic came. match.call() puts parentheses at the end of the name. I don't want parentheses in a filename. The following kludgey function gives the desired result.

Hi List, I have the following problem: I am using the multilevel package and make.univ function for available in the package and then xyplot from lattice and I want to know how could I be able to use the ?coefficient? for the straight line that passes the data ? Example from help: library(multilevel) data(univbct) #a data set already in univariate or stacked form for job satisfaction

Hello, I am a newbie to the lattice package in R, and I'm trying to make a plot using the xyplot function. I have repeated measures data (2 conditions) for two different groups of subjects (teens and adults). So far, I've made a basic graph using xyplot(y ~x, group=subnum, data=mydata, type="b"). Now I would like to make all the teens' lines one color and the adults'

Platform: WIN2000 Version of R: 1.6.2 I'm interested in plotting fitted values in a trellis xyplot. I believe the following should work; however, I only get the points (not the fitted lines). library(lattice) trellis.device(bg="white") xyplot(MULTDV~TIME|SUBNUM,data=TEMP, panel=function(x,y){ panel.xyplot(x,y) lines(x,fitted(lm(y~poly(x,1),na.action=na.omit)))

I've installed Samba ("latest") on SCO's openserver 5 with a WIN'95 hanging off of it as a client. I can run every test in DIAGNOSI.txt except for number 2. That is, the WIN'95 box can not ping the SCO box within a reasonable amount of time. (SCO can ping the WIN'95 box fine). For the longest time I thought the WIN'95 box couldn't ping the SCO box but I
