r - Reshaping block in data.frame to lists is columns uneven length -


i need r cast data:

    status     score  job.id  1   status1    99     job1 2   status1    99     job2  3   status1    99     job3 4   status1    99     job4 5   status2    36     job5 6   status2    36     job6 7   status2    49     job7 8   status2    58     job8 9   status2    64     job9

to wide form: 

    status1   status2 1   job1      job6 2   job2      job7 3   job3      job8 4   job4      job9 5   job5      <na>

i not need compute value, need make lists. ideally score used sort resulting lists. columns length uneven. unable find elegant answer elsewhere. thank you.

if want them in single data frame, this:

library(reshape2) library(plyr) dat <- read.table(text = "    status     score  job.id   1   status1    99     job1  2   status1    99     job2   3   status1    99     job3  4   status1    99     job4  5   status2    36     job5  6   status2    36     job6  7   status2    49     job7  8   status2    58     job8  9   status2    64     job9",header = true,sep = "") > dat <- ddply(dat,.(status),transform,ind = seq_along(status)) > dcast(dat,ind~status,fill = na,value.var = "job.id")   ind status1 status2 1   1    job1    job5 2   2    job2    job6 3   3    job3    job7 4   4    job4    job8 5   5    <na>    job9

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
