r - Add an arrow pointing at the x-axis in my plot in ggplot2 -


my goal arrow text pointing @ x-axis label average word frequency. cannot figure out life of me how either arrow or text outside of plotting area in ggplot2.

here code: 

ggplot(summary.pctdiff, aes(principle, pctdiff)) +xlab("principle")+ylab("% difference")+     geom_bar(aes(fill = sector),position = "dodge", stat="identity",col="black")+     ggtitle("how differing sectors talk different co-operative principles")+theme(plot.title=element_text(hjust=0.5),panel.border = element_rect(colour = "black", fill=na, size=1),legend.background = element_rect(color = "black"),legend.position =c(1.10,0.7),plot.margin=unit(c(0.5,3,0.5,0.5),"cm"))+     geom_hline(yintercept = 0)

here data: 

structure(list(principle = structure(c(1l, 2l, 3l, 4l, 5l, 6l,  7l, 1l, 2l, 3l, 4l, 5l, 6l, 7l, 1l, 2l, 3l, 4l, 5l, 6l, 7l, 1l,  3l, 4l, 5l, 6l, 7l), .label = c("principle 1", "principle 2",  "principle 3", "principle 4", "principle 5", "principle 6", "principle 7" ), class = "factor"), pctdiff = c(-6.71369900758148, 9.44233503731219,  11.0107840625484, -53.1259224412594, -9.22356636157099, -41.0142340880256,  -9.6288000905822, -55.3759198976217, -19.1012386886889, -75.4996296064581,  -44.7688906852688, -58.5771031808126, 48.9559446961189, 4.52522805921763,  29.4368505336144, 51.7181015822617, -2.26377179780978, 48.1990295720174,  57.4736669182075, 8.41689226435695, -15.8983115124042, 30.6261564806236,  79.5018869249509, 87.2542807992621, -15.3228747516659, 13.5915020818539,  48.2301858238767), sector = c("ag", "ag", "ag", "ag", "ag", "ag",  "ag", "fin", "fin", "fin", "fin", "fin", "fin", "fin", "serv",  "serv", "serv", "serv", "serv", "serv", "serv", "other", "other",   "other", "other", "other", "other")), .names = c("principle",   "pctdiff", "sector"), row.names = c(na, -27l), class = "data.frame")

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
