R语言绘制散点图时自定义坐标轴标签与默认标签重叠如何解决

出现标签重叠的核心原因是：R的plot()基础绘图函数默认会根据传入的变量名自动生成坐标轴标签，后续调用title()函数相当于在原有标签的基础上额外新增标签，二者位置接近就会出现重叠。

两种修复方法 #

• 方法1（更推荐）：直接在plot()函数内一次性配置所有标题、标签参数，不需要额外调用title()

#Create scatter plot number 1
#x = Written Frequency, y = RTlexdec
plot(dataset$WrittenFrequency, dataset$RTlexdec,
     main = "Scatter plot 1: WrittenFrequency & RTlexdec",
     xlab = "WrittenFrequency",
     ylab = "RTlexdec")

• 方法2：如果需要单独调用title()配置，需要先在plot()中关闭默认标签生成

#Create scatter plot number 1, disable default axis labels
#x = Written Frequency, y = RTlexdec
plot(dataset$WrittenFrequency, dataset$RTlexdec, xlab = "", ylab = "")
#Call title() function to label axes and give a title
title(main = "Scatter plot 1: WrittenFrequency & RTlexdec ", sub = NULL, xlab = "WrittenFrequency", ylab = "RTlexdec")

补充提示：你原代码中title()里的xlab、ylab的标注写反了，x轴对应自变量WrittenFrequency，y轴对应因变量RTlexdec，建议调整避免图表语义错误。
