Array Indexing Round 4 R Programmerhumor It comes from using the array syntax as an offset of a pointer. ptr [0] accesses the memory at adress ptr with an offset of 0. [text] arrays starting with o arrays starting with 1 arrays starting with 2 arrays starting with 1 hashmaps starting with int first second third fourth fifth sixth seventh eighth ninth tenth eleventh twelfth thirteenth fourteenth fifteenth t sixteenth seventeenth eighteenth nineteenth twentieth array arrays.
Array Indexing Round N R Programmerhumor From experience with other languages, i would think x[1, 2], rather than x[2, 1], would be 2, but this is pretty easy to adjust my thinking to. however, just as quickly as i perform my mental model shift, the next example smashes it apart: > i < array(c(1:3,3:1), dim=c(3,2)) > i # i is a 3 by 2 index array. [,1] [,2]. I ended up making a casual comment that in the context of programming, the 0 based indexing is much better stylistically than 1 based indexing for things like conditional checks and start end indexing. Ah, the classic programmer joke about array indexing! the medal shows "1 place" but someone cuts out the "1" to make it "0 place" because in most programming languages, arrays start at index 0, not 1. To index elements use square brackets: ar[1], or ar[1,1] for 2d. whole columns and rows are: ar[,1] or ar[1,] for sorting, look at the sort and order functions. for calculations using 2d arrays, you can have: elementwise: ar1 ar2, ar1*ar2. inner product: ar1%*%ar2. outer product: outer(ar1,ar2) or ar1%o%ar2.

This problem could arise when a programmer makes mistakes such as using "is less than or equal to" where "is less than" should have been used in a comparison or fails to take into account that a sequence starts at zero rather than one (as with array indices in many languages). When your girlfriend questions her position in your life, just tell her she's at index [1] in your array of interests. she'll think she's second place, but little does she know arrays start at 0, making her actually second to last in your priority list.
