R.java error. dont know where is came from. dont know how to fix it
Date : March 29 2020, 07:55 AM
I think the issue was by ths following , You have an id somewhere defined as @+id/1. 1 does not make for a valid Java identifier, hence the error. For that same reason, one cannot create ids or resources which name starts with a number, or contains spaces, or matches a reserved keyword.

TChart - Dont plot values that are less than 0?
Tag : delphi , By : user185949

help you fix your problem You have the possibility when adding values to a series to add them as null. This will prevent them from showing. Series1.IgnoreNulls := False;
if (y < 0) then
Series1.AddNullXY(x, y, '')
else
Series1.AddXY(x, y, '');

private $events;
public function __construct($events)
{
$this->processData($events);
}
public function processData($data)
{
foreach($data as $event)
{
$this->processEvent($event);
}
}
public function processEvent($event)
{
$this->events[$event->id]['name'] = $event->name ?: 'Event name not found';
$this->events[$event->id]['teacher'] = $event->teacher ? $event->teacher->toArray() : array('name', 'Teacher not found');
}
public function getData()

Plot multiple barplots on one plot, but bars dont overlap R

this one helps. If you're doing something like this, I'd recommend using ggplot2, as it's much easier. Here's some sample code: library(ggplot2)
data(diamonds)
ggplot(diamonds,aes(x=carat,y=price,fill=color))+
geom_histogram(stat='identity')+
facet_grid('cut~.',scale='free')+labs("Graph Title")

How to plot multiple SpatialLines on the same plot: Error in plot.new() : figure margins too large
Date : March 29 2020, 07:55 AM
Hope that helps I sometimes get this error as well and I maximize my X11 plotting window and it goes away (I don't use RStudio often though). The code you provided works fine for me even in the default size viewer. This code produces 3 plots though. You could make them on the same plot by using the parameter new in par plot(spl)
par(new=TRUE)
plot(spl90)
par(new=TRUE)
plot(spl180)
par(new=FALSE)
