Hello, Let's assume I have a vector of integers : > myvector <- c(1, 2, 3, 2, 1, 3, 5)
My purpose is to obtain the cumulative distribution of these numerical data, i.e. something like : value nb_occur. <=1 2 <=2 4 <=3 6 <=4 6 <=5 7 For this, I create a table with ; > mytable <- table(myvector) 1 2 3 5 2 2 2 1 However, table() returns an array of integers, mytable[4] returns the occurence number of the "5" item, which makes this table hard to index. I would prefer to have a data structure where mytable[4] could return 0, as there is no "4" in my vector. table() may not be the proper way to do it. For the moment, I use a loop which scans the vector from its lowest value to its highest, and counts the number of times each value appears. Is there a built-in function, or a table() option to do such a task ? Thanks.
