A querent on StackOverflow asked about the with() function http://stackoverflow.com/questions/42283479/why-when-to-use-with-function#42283479
and asked about the example in ?with library(MASS) with(anorexia, { anorex.1 <- glm(Postwt ~ Prewt + Treat + offset(Prewt), family = gaussian) summary(anorex.1) }) which saves little or no typing relative to anorex.1 <- glm(Postwt ~ Prewt + Treat + offset(Prewt), family = gaussian, data=anorexia) (I would argue that the latter is better practice anyway). Could we have something more sensible like with(mtcars,mpg[cyl==8 & disp>350]) ? (It could be contrasted directly with mtcars$mpg[mtcars$cyl==8 & mtcars$disp>350] ) I'm happy to submit a bug report/patch if that seems appropriate. cheers Ben Bolker ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
