A bootstrap of mtcars$mpg in a for loop runs longer than meant, in webRios on an iPhone. One tap on Stop ends the run.
length(boot) shows the 624,560 resamples it finished, and hist() draws them.
webRios is an R editor for iPhone and iPad. It uses webR, the WebAssembly version of R, to run your code on the device itself, with no server behind it. You must have an iPhone/iPad with at least iOS 26 or iPadOS 26.
