.. changed the indexing operators [ ] to work solely with vectors. so it is now possible to reference an element in a vector: a<-c(1,2,3,4); b<-a[1] will assign the value 2 to variable b. .. additionally you can assign to an element of a vector, following on from above: a[0]<-99; will mean a how has 4 elements: [99, 2, 3, 4] .. lastly you can use [] with an expression, so: c(1,2,3,4)[2] evaluates as value 3.
