[R] Windows Installation Without Third-Party Packages

I am trying to install R for Windows, but when I use the installer provided on CRAN, a number of third-party packages are installed by default (i.e. lattice, Matrix, codetools, etc.). If R is installed with administrator privileges, so it's available for all users, non-administrators can't update

[R] Tight Axes in Prepanel Function

How do I specify a tight y-axis, where the plot completely fills the y-axis range, inside the prepanel function? For example, consider the following code: require(lattice) set.seed(12345) x - 1:1000 y - cumsum(rnorm(length(x))) prepanel.test - function(x, y, groups = NULL, subscripts = NULL,

When using the 'splom' function of the 'lattice' packge, is it possible to get all the tick marks in the outer margins of the plot? X - as.data.frame(matrix(rnorm(1000), 100, 10)) plot(X) ## Tick marks are in the outer margin splom(X) ## Tick marks are inside the on-diagonal panels Thanks. -

I'm trying to write a generic function that calls different methods depending on the structure of the argument, but not the exact type of its contents. For example, the function 'nan2last' below works for a numeric vector but not for a vector of Date objects. Is there any way to make it work on
