Hello R helpers, I am producing a figure with dual strips, i.e., x~y | S1 + S2, where S1 and S2 are two strips. For example, in figure 2.1 at http://lmdvr.r-forge.r-project.org/figures/figures.html. In this case, I would like to combine the the top strip, since all three pictures in the same row have the same level based on the first strip. In other words, instead of | -- S11 -- | -- S11 -- |

Hey R-users, I think I followed the steps but still couldn't figure this out.. I am creating a personal package and I want to include several datasets in the package. I created a subdirectory 'data' in the package, save a dataset 'test.rda' there, built the package, checked it, installed it. Then I loaded the package and tried load(test), data(test), attach(test), none of them

Hi all, I know pnorm() is able to calculate a sequence of probabilities by providing a vector of means, and a single number for location and standard deviation. For example, pnorm(0.5,c(0.5,2),1) will produce [1] 0.5000000 0.0668072. However, I wonder if its multivariate counterpart mvtnorm can do the same thing? Namely, if I provide a sequence of (vector-)means and a single vector for
