R Merge Dataframe -


i have multiple data frames have same column headers want append them 1 after other make 1 big dataframe. best way this.

i used following: not sure right way do:

append(x, y)

i tried rbind ended following error expected since these data frames have different length in size:

error in names(value[[jj]])[ri] <- nm :    'names' attribute [2066] must same length vector [9] in addition: warning message: in names(value[[jj]])[ri] <- nm :   number of items replace not multiple of replacement length

here example:

> x   user_id rev_page   rev_id rev_parent_id page_ns rev_length delta deleted rev_curr_minor           timestamp edit_count lang_level 1  705834  1048946 32026867      30924739       0       2959    82       0              0 2005-12-19 23:21:24          0          n 2  705834  1048946 32028621      32026867       0       3085   126       0              0 2005-12-19 23:36:33          1          n 3  705834    21402 32032828      32027632       0      14395   470       0              0 2005-12-20 00:10:06          2          n 4  705834    21402 32033273      32032828       0      14400     5       0              0 2005-12-20 00:13:50          3          n 5  705834   321528 32065506      29330826       0       3440   201       0              0 2005-12-20 05:13:45          4          n 6  705834   321528 32066086      32065506       0       3525    85       0              0 2005-12-20 05:21:25          5          n > y   user_id rev_page   rev_id rev_parent_id page_ns rev_length delta deleted rev_curr_minor           timestamp edit_count lang_level 1  892755  2585151 38515111      24830760       0       2018  1213       0              0 2006-02-06 21:32:26          0          1 2  892755  3807359 63798071      63471532       1      14047  5293       0              0 2006-07-14 15:46:56          1          1 3  892755  3807359 63798564      63798071       1      14146    99       0              0 2006-07-14 15:49:52          2          1 4  892755  2976438 63825832      44108751       0       9609   -60       0              0 2006-07-14 18:38:41          3          1 5  892755  3807359 63891769      63855569       1      15579  1005       0              0 2006-07-15 02:28:59          4          1 6  892755  3807359 67487579      63891769       1      15745   166       0              0 2006-08-03 18:52:01          5          1 > class(x) [1] "data.frame" > z <- rbind(x,y) error in names(value[[jj]])[ri] <- nm :    'names' attribute [12] must same length vector [9] in addition: warning messages: 1: in names(value[[jj]])[ri] <- nm :   number of items replace not multiple of replacement length 2: in names(value[[jj]])[ri] <- nm :   number of items replace not multiple of replacement length > rbind(x,y)

if columns in same order (following @matthewplourde's comment), rbind(df1,df2,df3,...).

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
