R - cluster analysis on binary weblog data -


i have web data looks similar sample below. has user , binary value whether user cliked on particular link within website. wanted clustering of data. main goal find similar users based on online behaviour. clustering alorithm this? have tried k-means not work binary data. have tried spherical k-means skmeans(). wanted sum of squared error scree plot, not figure out how sse skmeans.

   user   link1 link2 link3 link4     abc1     0     1     1     1     abc2     1     0     1     0     abc3     0     1     1     1     abc4     1     0     1     0

you try hierarchical clustering using binary distance measure jaccard, if "clicked link" asymmetrical: 

dat <- read.table(header = true, row.names = 1, text = "user   link1 link2 link3 link4 abc1     0     1     1     1 abc2     1     0     1     0 abc3     0     1     1     1 abc4     1     0     1     0") d <- dist(dat, method = "binary") hc <- hclust(d) plot(hc)

enter image description here

(clusters <- cutree(hc, k = 2)) # abc1 abc2 abc3 abc4  #    1    2    1    2

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
