我想让 r 条形图的图例框水平，但 ncol 不起作用

如何解决我想让 r 条形图的图例框水平，但 ncol 不起作用

这是我用于绘图的代码

barplot(read_comments_vs_influenced,xlab='Do you usually read comments under YouTube video clips?',ylab='Count',main=str_wrap("How far comments influence respondents' opinion for each category in reading  comments under Youtube videos",width = 110),legend=rownames(Age_vs_platform_follow_artists),args.legend = list(x = "topleft",cex = 0.4) ) 

我想让图例框水平以适合图表或在不影响图例内字体大小的情况下使框变小 我尝试使用 ncol=3 但它给了我一个错误：ncol not agraphical argument

解决方法

这应该有效：

barplot(read_comments_vs_influenced,xlab='Do you usually read comments under YouTube video clips?',ylab='Count',main=str_wrap("How far comments influence respondents' opinion for each category in reading  comments under Youtube videos",width = 110)
        )

legend("topleft",legend = rownames(Age_vs_platform_follow_artists),ncol = 3,cex = 0.4)

也许 ncol 放在括号的错误一侧？
