i have data frame 3262 rows , 10 columns. 1 of columns has date format yy-mm-dd . want store rows 10 different dates in different data frame tried : newdata= df[df$date %in% as.date(c('2011-08-05','2012-1-13','2012-03-2','2014-04-01')),] but nothing. thought might need specify again format tried: df$date <- as.date( as.character(df$date), "%d-%m-%y") newdata= df[df$date %in% as.date(c('2011-08-05','2012-1-13','2012-03-2','2014-04-01')),] all empty data frame saying no data available in table . @ point made mistake (something stupid guess)? i created example: set.seed(1) df=data.frame(col1=seq(1,10), col2=seq(1,0), date=as.date(floor(runif(min=15550,max=17000,n=10)),origin="1970-01-01")) > df col1 col2 date 1 1 1 2013-08-17 2 2 0 2014-01-19 3 3 1 2014-11-06 4 4 0 2016-03-06 5 5 1 2013-05-17 6 6 0 2016-02-21 7 7 ...

i use chocolatey install/update applications on pc. there way make sure packages install have been approved moderators? if choco install <package name> might warning package not trusted , press n or y continue, it's tedious task confirm each package. there simpler way this? i'm looking parameter can set -autodenyuntrustedpackages ? a side note, know can use chocolateyui, never prompts regarding untrusted packages. due security flaw or allow updates if update has been verified moderator? in order install package not yet verified moderator, you have specify version . these packages not installed or updated automatically, meaning actual behavior describe implemented default. trusted packages mean else: packages come trusted source (like creator of program package installs). these packages skip human moderation.

i need keycode corresponding structure linux/input.h after keyevent android. i'm simulating keyboard in jni android. here part of code code : void keyboardpress(int character) { memset(&ev, 0, sizeof(struct input_event)); ev.type = ev_key; ev.code = character; ev.value = ev_pressed; write(fd, &ev, sizeof(struct input_event)); dev_uinput_sync(fd); ev.type = ev_key; ev.code = character; ev.value = ev_released; write(fd, &ev, sizeof(struct input_event)); dev_uinput_sync(fd); } the value character must value struct linux/input.h example if press 'q', in java code value : public static final int keycode_q = 45; the value of 'q' in linux/input.h : #define key_q 16 is possible value of linux/input.h of character java code or convert java keyevent code linux/input.h code ? thank !

would possible use wildcard in if statement this? if(trim($line) != $delete) full code: $delete = "*totalwar"; $data = file("../oneos/applist.txt"); $out = array(); foreach($data $line) { if(trim($line) != $delete) { $out[] = $line; } } $fp = fopen("./foo.txt", "w+"); flock($fp, lock_ex); foreach($out $line) { fwrite($fp, $line); } flock($fp, lock_un); fclose($fp); i complete php noob, php way see project working. need user able delete line in text file, no matter infront of text enter. example, if user enters delete totalwar , text file looks this: set app24=totalwar , need script delete entire line. you can use fnmatch() this fnmatch() checks if passed string match given shell wildcard pattern. for more info read http://php.net/fnmatch
