At n = 0, Rnorm returned FALSE and Rgamma, Rgamma0\nand Rbeta one deviate for most shapes; all give numeric(0) now.\n\nHangs and crashes on valid input: SQRT(Inf) never returned, because\nNORM's halving loop cannot end on Inf, and NORM looped forever on any\nnegative x. SQRT(Inf) is Inf with the warning EXP and LOG give; NORM\nstops with a message on a non-finite x and gives a negative fraction\nfor a negative one. evJacobi stopped with \"object 's' not found\" on\nmatrices such as diag(c(2, 1)), testing the rotation sine on a pair\nthat needed no rotation. VMmin never returned when its direction right\nafter a reset was not downhill, as at a zero gradient: SmallXcount was\nmisspelt. Optim0 stopped on \"object 'RelStep' not found\" when it ended\non its first iteration, MachEps3 and MachEps4 on 'CurEps' at\nMaxIter = 0. Dec2Bin(0) returned NaN bits, and Run.test a p-value of 2\nwhen no nonzero value was left (now NA).\n\nGiven NA, EXP, LOG and SQRT stopped with R's generic missing-value\nerror, and SQRT did for NaN; they now return what exp, log and sqrt do.\n\nRmvn checks its n, which it hands to Rnorm, and trapez1 and romb check n\nand N, which the fixes above made drive an if: 142 argument positions\nacross 70 functions, each named on its help page.\n\nEvery fix has an assertion in tests/regression.R. Checked against\nindependent references, and about 49,000 cases that returned under the\ntagged build give identical() results, warnings and random draws.\nR CMD check", "time": 1791612924 },
