r - How to make a density plot in ggplot2 with dates on the x-axis -


i have dataframe df column time contains r date objects , want plot density plot see days had activity. don't want convert timestamps, because prefer more meaningful labels in x-axis.

my attempt

here trying:

ggplot(df, aes(x = time)) + geom_density(stat="identity") + scale_x_date()

which gives error

error in as.environment(where) : 'where' missing

here output of dput(df):

structure(list(time = structure(c(15863, 15887, 15865, 15873, 15885, 15878), class = "date")), .names = "time", row.names = 8831395:8831400, class = "data.frame")

for reason argument stat_density causing ggplot lose way among environments set up. (at least that's "where" missing error comes from.) succeeds:

 ggplot(df, aes(x = time)) + geom_density()

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...
