[R] is it possible to map 2 plots(c and d) in a single output plot?

is it possible to map 2 plots(c and d) in a single output plot? library(ggplot2) c <- ggplot(mtcars, aes(qsec, wt)) d <- ggplot (mtcars, aes(qsec, wt)) c + stat_smooth(fill="darkgrey", colour="blue", size=2, alpha = 0.2) d + stat_smooth(fill="darkgrey", colour="red", size=2, alpha = 0.2) -- View

[R] small change in output

For every specific V1 and V4 pair (ex:A and P) calculate Linear regression of V3(y-axis) and V2(x-axis) and print p value along with the pair (output). INPUT # V1 V2 V3 V4 A 1 2.5 P A 2 2.8 P A 3 3.2 P A 2 1.1 Q

Re: [R] liner regression for multiple keys

Hi Ben it's working good except no values of 4th column in output. And also if the file is large I'm getting the following error. Error in pf(q, df1, df2, lower.tail, log.p) : Non-numeric argument to mathematical function I rechecked if I have any non numeric arguments the defined columns. I

[R] liner regression for multiple keys

a1 is the first key in input. second column is x-axis and 3rd is y-axis and 4th is its corresponding key. Now for every key in 1st column I would like to calculate LR that gives p value. I tried to manage with a single key. But my problem is that How could I manage multiple keys in input. Thanx in

[R] make.groups function of laatice is not working?

I almost wasted 3 hours to make lattice functions work. :(. Phew! I installed package lattice, lattice extra and other supportive packages to use functions 1.make.groups 2.forplot 3.xyplot. I also tried local installing. They are installing very well but not working? Any one have any idea why R
