r - EyetrackingR: make_eyetrackingr_data -- subscript out of bounds -


i using eyetrackingr package (http://www.eyetracking-r.com/workflow) analyse data. package includes function called make_eyetrackingr_data using raw data (all_kids).

the code type in looks this:

data <- make_eyetrackingr_data(all_kids,                             participant_column = "subject",                            trial_column = "trialid",                            time_column = "tettime",                            trackloss_column = c('validitylefteye','validityrighteye'),                            aoi_columns = c('targetlook','distractorlook'),                            treat_non_aoi_looks_as_missing = true)

the output r gives me is:

converting trial proper type. converting trackloss proper type. converting trackloss proper type. converting aoi proper type. converting aoi proper type. error in .subset2(x, i, exact = exact) : subscript out of bounds

now, apparently there sort of problem data frame being large or (as can tell quite new whole r world). know there functions test if frame large, have no clue how works.

any appreciated

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...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
