Slight oversight in the type documentation
So I was looking at the type reference, and noticed that for a lot of the types, no namevar was listed. When I checked the types in the code, for each of those omissions, the namevar was simply "name". Now, it might be self evident that this is the case, but a little documentation couldn''t hurt, If not in each type, at least in the section where it describes what namevars

Checking for orthogonal contrasts

Documentation examples for lm and glm
...k who have a data frame but want to reference the contents across a wider range of functions without using with() a lot. lm() can reasonably omit the data argument there, too. So while there are good reasons to use data frames, there are also good reasons to provide examples that don't.

Question regarding dnorm()
Hi, I have one basic doubt. Suppose X ~ N(50,10). I need to calculate Probability X = 50. dnorm(50, 50, 10) gives me [1] 0.03989423 My understanding is (which is bit statistical or may be mathematical) on a continuous scale, Probability of the type P(X = .....) are nothing but 1/Infinity i.e. = 0. So as per my understanding P(X = 50) should be 0, but even excel also gives 0.03989422. Obviously
