r - Slidify Quiz Answer is of Character Class -

i'm using bundle slidify written ramnath vaidyanathan. creating first quiz using widget [quiz].

--- &multitext 1. create vector x of length three, must consist of next values 2 , 3, , 7. *** .hint utilize command c() *** .explanation 1. <span class="answer">x<-c(2,3,7)</span>

this fine, in text-input area, if type x<-c(2,3,7) reply wrong icon. working numeric class? possible implement character class quiz?

currently, widget setup take numeric answers. easy enable character input, believe unreliable. example, user can type different answers, character-wise , correct.

x <- c(2, 3, 7) x<-c(2,3,7) x<-c(2,3, 7)
