element_text()gains a margins argument which allows you to add additional padding around text elements. To help see what's going on usedebug = TRUEto display the text region and anchors. The default font size ingeom_text()has been decreased from 5mm (14 pts) to 3.8 mm (11 pts) to m...

在ggplot2中,element_rect()函数用于定义矩形元素(如背景、边框等)的样式。针对你的问题,我将分点进行回答: element_rect()函数中size参数的用途: 在早期的ggplot2版本中,element_rect()函数的size参数用于控制矩形边框的粗细。例如,如果你想设置图例背景的边框粗细,可以使用size参数来调整。 r # 假设这是旧版本...
