Stephanie, Actually, it's as.logical that isn't preserving matrix dimensions, because it coerces to a logical vector: > x <- matrix(sample(c(NA_integer_, 1:100), 500, replace=TRUE), nrow=50) > dim(as.logical(x)) NULL ~G On Tue, Mar 3, 2015 at 2:09 PM, Stephanie M.

In my own package, I want to use the default S3 method of the generic function lrtest() from the lmtest package. Since I need only one function from lmtest, I tried to use importFrom in my NAMESPACE: importFrom(lmtest, lrtest) However, this fails R CMD check in the examples: Error in UseMethod("lrtest") : no applicable method for 'lrtest' applied to an object of class

I am trying to build a package (GWASTools, submitted to Bioconductor) that uses the "sandwich" package. I have references to "sandwich" in DESCRIPTION: Imports: methods, DBI, RSQLite, sandwich, survival, DNAcopy and NAMESPACE: import(sandwich) In the code itself is a call to vcovHC: Vhat <- vcovHC(mod, type="HC0") I have sandwich version 2.2-7 installed.
