Hello, I'm trying to get the count of values in each row that are above and below quantile thresholds. Thanks!
Example: > x = matrix(1:30,5,6) > x [,1] [,2] [,3] [,4] [,5] [,6] [1,] 1 6 11 16 21 26 [2,] 2 7 12 17 22 27 [3,] 3 8 13 18 23 28 [4,] 4 9 14 19 24 29 [5,] 5 10 15 20 25 30 > qtl = t(apply(x, 1, quantile, probs = c(.1,.9),na.rm=T)) > qtl 10% 90% [1,] 3.5 23.5 [2,] 4.5 24.5 [3,] 5.5 25.5 [4,] 6.5 26.5 [5,] 7.5 27.5 I would like counts like this for each row: cnts [,1] [,2] [1,] 1 1 [2,] 1 1 [3,] 1 1 [4,] 1 1 [5,] 1 1 ...because for the first row (x[1,]) only value 1 is less than 3.5 and only value 26 is greater 23.5 and so on for the other rows. I'm thinking its a apply(x,1,...some FUN here...), but still getting use to apply and I've been coding for too long... Also, if anyone knows how to change the background color of the r-Tinn editor my eyes would love you! Off to bed. I look forward to your answers! Thanks!
