在R语言中,如果你想要使用ggplot2库创建图形并删除图例、标题或者坐标轴的边框线,可以这样做:
1. 图例边框:在`theme()`函数中添加`strip.background = element_blank()`,这会去除图例背景及其边框。例如:
```r
ggplot(data, aes(x, y)) + geom_point() +
theme(strip.background = element_blank(), legend.position = "none")
```
2. 标题和轴标签边框:`plot.title`、`axis.title`和`axis.text`可以在`theme_minimal()`等主题中设置为`element_text()`,然后通过`colour = "transparent"`使其透明。例如:
```r
ggplot(data, aes(x, y)) + geom_point() +
theme(plot.title = element_text(colour = "transparent"),
axis.title = element_text(colour = "transparent"),
axis.text = element_text(colour = "transparent"))
```
3. 整体图表边框:如果想删除整个图表的边框,可以加上`plot.margin = unit(c(0, 0, 0, 0), "lines")`,将所有边距设为0。例如:
```r
ggplot(data, aes(x, y)) + geom_point() +
theme(plot.margin = unit(c(0, 0, 0, 0), "lines"))
```
