3-D bar plots are an abomination. Just because Excel can do them doesn't mean you should.

Basically R is reluctant to let you shoot yourself in the foot unless you are really determined to do so.

Weird. Over at ESS they discuss how to debug with %>% when I always thought that having %>% was the bug.

Note that there is a reasonable discussion in Writing R Extensions, but as always, you have to find it first.

EnTyrely Too Much https://link.rweekly.org/cv3 #rstats #datascience

A sufficiently trained statistician can read the vagaries of a Q-Q plot like a shaman can read a chicken's entrails, with a similar recourse to scientific principles. Interpreting Q-Q plots is more a visceral than an intellectual exercise. The uninitiated are often mystified by the process. Experience is the key here.

JPM Miao: Why can't R understand if(num!=NA)?
Peter Dalgaard: Because comparison with an unknown value yields an unknown result.
David Winsemius: Anything else would violate the Second Law of Thermodynamics. We cannot have comparisons reducing entropy, now can we? Uncertainty cannot run uphill.
-- JPM Miao, Peter Dalgaard, and David Winsemius (on why is.na() is needed)

As one of the developers of the nls function I would like to state that the lack of automatic ANOVA, R^2 and adj. R^2 from nls is a feature, not a bug :-)

It is becoming apparent that you do not know how to use the results from either system. The progress of science would be safer if you get some advice from a person that knows what they are doing.
-- David Winsemius (in response to a user that obtained different linear regression results in R and SPSS and wanted to know which one to use)

I wish there was a better way for me to learn this stuff than constantly being wrong in public.
