...ue in that table. The other table contains a number of socio-economic variables for each of the geographic areas identified in the other table. This second table also includes a variable called dacode and I have also used dacode for the rownames. I want to pull a number of the variables from the socioeconomic status data into the first table but I'm having no luck. Here's what I have tried so far: #first attempt grade6DA$ses1 <- sesdata$ses1[as.character(grade6DA$dacode)] All that this does is create a new column in the grade6DA data set and calls it ses1 but then fills it with NA....

This is a question relating to the Trellis function in R. I have a set of socioeconomic data that I would like to display with the xyplot() function for several states. I will have a total of 6 plots, with the y-variable as "Age Group", and the x-variable as "Median Income". Suitability of the plots aside (this cannot be changed), I need to plot the points of one...

I've sometimes thought it would be useful to have another mail list called "no I haven't read the documentation but someone can save me a lot of time," or perhaps just "newbie" for short. This can be very useful for people just getting started in R and with school starting soon I expect the help list may become overwhelmed. Of course, I think that people should read all

Dear All, I'am looking for examples showing that correlation does not imply causality, the targeted audience consists of undergraduate students (their first year at the university but in the BioMathStat track). All practicals are under R. I was able to extract this from R datasets: ### begin data(sunspots) data(lynx) spots <- window(sunspots, freq = 1, start = 1880, end = 1900) lnx <-
