fill

I have to make a function that takes an empty list as first argument and n as secound argument, so that: L=[] function(L,5) print L returns: [1,2,3,4,5] I was thinking: def fillList(listToFill,n): listToFill=range(1,n+1) but it is returning an empty list. Consider the usage of extend : >>> l = [] >>> l.extend(range(1, 6)) >>> print l [1, 2, 3, 4, 5] >>> l.extend(range(1, 6)) >>> print l [1, 2, 3, 4, 5, 1, 2, 3, 4, 5] If you want to make a function (doing the same): def fillmylist(l, n): l.extend(range(1, n + 1)) l = [] fillmylist(l, 5) A function without an explicit return or yield returns

I have a zoo time series with missing days. In order to fill it and have a continuous series I do... I generate a chron date-time sequence from start to end. I merge my series with this one. I use na.locf to substitute NAs with las obsservation. I remove the syntetic chron sequence. Can I do same easier? Maybe with some index function related to the frequency? It's slightly easier if you use a "empty" zoo object with an index. > x <- zoo(1:10,Sys.Date()-10:1)[c(1,3,5,7,10)] > empty <- zoo(order.by=seq.Date(head(index(x),1),tail(index(x),1),by="days")) > na.locf(merge(x,empty)) 2010-08-14 2010

I've seen at least two recommendations on StackOverflow to insert newlines between sentences when editing LaTeX documents. The reason being that the practice facilitates source control, diff ing, and collaborative editing. I'm basically convinced, but I'm lazy, and I don't want to have to think about it. So I'm searching for some emacs incantation to handle it for me. Could be a minor mode, could be a set of variables that need to be set. I think what I don't want is Soft wrapping of text (say using the longlines and (set long-lines-auto-wrap 't) ). This is because I don't want to impose

I'm trying to fill an array in spiral order. So far, I can print the array in spiral order, but is there a way to modify the array so that i can fill it in spiral order and then just print the array? I'd like it to go in decreasing order like a countdown. Please help! public class Spiral { public static void main(int m, int n) { // create m by n array of integers 1 through m*n int[][] values = new int[m][n]; for (int i = 0; i < m; i++) for (int j = 0; j < n; j++) values[i][j] = 1 + (m*n)*i + j; // spiral for (int i = (m*n)-1, j = 0; i > 0; i--, j++) { for (int k = j; k < i; k++) System.out

I have following data and code: > mat <- matrix(c(120,230,84,70,130,83,13,26,18),3) > dimnames(mat) <- list(c("good","fair","poor"),c("a","b","c")) > mat > mat a b c good 120 70 13 fair 230 130 26 poor 84 83 18 > > chisq.test(mat) Pearson's Chi-squared test data: mat X-squared = 11.411, df = 4, p-value = 0.02231 > library(vcd) > mosaic(mat, shade=T) The chi-squared test shows significant difference but no color is seen since residuals are small. With higher residuals, colors are seen: ?mosaic shows this information: highlighting_fill: color vector or palette function used for a highlighted
