#RStats #Rprogramming Does anyone know why the below comparisons fail to return TRUE in R? x = seq(from = 0, to = 1, by = 0.05) # the following seem to fail (at least in R 4.2.1) x[4] == 0.15 x[7] == 0.30 identical(x[4], 0.15) # but this one works all.equal(x[4], 0.15)

It is a rite of passage. Program sufficiently much with #rstats and you will most likely fall into an 'R FAQ 7.31'-shaped hole. Holds with other programming languages too, unless you operate symbolically.

It's a deep hole for non-CS folks, too.

Indeed. And perhaps the worst part is the frustration and headaches experienced by my students, who for the most part are non-CS folks.
