Does anything change if you use the development version of Rdpack (not currently on CRAN)? Apparently, the latest commit performs some

This is a known issue already reported to the Rdpack maintainer. In some cases, the Rd code generated by Rdpack's macros contains unnecessary braces that trigger the check note because they match the pattern "text{text}" that detects common mistakes like "code{x}" (missing an escape for the macro name).

I apologize for accidentally omitting some of the answers I got; here they are: ************** I use R regularly in my research in the pharmaceutical industry. I have used it for projects ranging from sample size and power curve estimation, analysis of laboratory data with mixed effects models, to analysis of mass spectrometry data. I have helped biologists here install and use it in limited

Question for 'experts' in LP using R (using the lpSolve package, say) -- which does not apply to me for the sort of problem I describe below. I've run any number of LP's using lpSolve in R, but all of them to date have objective and constraint functions that both contain the same variables. This lets you set up a LHS and RHS matrix/vector that are symmetrical. But, for a
