r - strwidth: How to get the correct width for umlauts and other accented/special characters? -


consider following example:

txt <- c("abc", "äéß") nchar(txt) # [1] 3 3 strwidth(txt, units = "inches", family = "mono") # [1] 0.4166667 0.8333333 plot(0, type = "n"); text(1, c(0, .3), txt, family = "mono", cex = 5)

i'd have expected strwidth return [1] 0.4166667 0.4166667 when using nonproportional font. can expected output without replacing non-ascii characters? help.

session info: r version 3.1.3 (2015-03-09), platform: x86_64-w64-mingw32/x64 (64-bit), running under: windows 7 x64 (build 7601) service pack 1, locale: lc_collate=german_germany.1252, lc_ctype=german_germany.1252, lc_monetary=german_germany.1252, lc_numeric=c, lc_time=german_germany.1252

edit:

as noted in comments, strwidth problem seems known rstudio issue.

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.
