Hi there, Here is a minimum working example: ---------------------------------------------------------------- lower = 0 upper = 1 n_bins = 50 interval = (upper - lower) / n_bins bins = vector(mode="numeric", length=n_bins) breaks = seq(from=lower + interval, to=upper, by=interval)
for(idx in breaks) { bins[idx / interval] = idx } print(bins) ---------------------------------------------------------------- which outputs: ---------------------------------------------------------------- [1] 0.02 0.04 0.06 0.08 0.10 0.14 0.00 0.16 0.20 0.00 0.22 0.24 0.26 0.28 [15] 0.30 0.32 0.34 0.36 0.38 0.40 0.42 0.44 0.46 0.48 0.50 0.52 0.54 0.56 [29] 0.58 0.60 0.62 0.64 0.66 0.68 0.70 0.72 0.74 0.76 0.78 0.80 0.82 0.84 [43] 0.86 0.88 0.90 0.92 0.94 0.96 0.98 1.00 ---------------------------------------------------------------- It turns out that some elements are incorrect, such as the 6th element 0.14, which should be 0.12 in fact. Is this a bug or I am missing something? And here is the output of sessionInfo(): ---------------------------------------------------------------- R version 2.15.0 (2012-03-30) Platform: x86_64-pc-mingw32/x64 (64-bit) locale: [1] LC_COLLATE=Chinese (Simplified)_People's Republic of China.936 [2] LC_CTYPE=Chinese (Simplified)_People's Republic of China.936 [3] LC_MONETARY=Chinese (Simplified)_People's Republic of China.936 [4] LC_NUMERIC=C [5] LC_TIME=Chinese (Simplified)_People's Republic of China.936 attached base packages: [1] stats graphics grDevices utils datasets methods base loaded via a namespace (and not attached): [1] cubature_1.1-1 tools_2.15.0 ---------------------------------------------------------------- Thanks in advance.
