win10,Rstudio 1.0.143,输入boxplot(wind~month, airquality, xlab="month", ylab="wind speed")报错:Error in eval(predvars, data, env) : object 'wind' not found,但是输入boxplot(airquality$Wind~airquality$Month,xlab="month",ylab="wind speed")正常显示,为什么?
先把数据读进去
你遇到过这个问题吗?解决不了
boxplot(Wind~Month, airquality, xlab="month", ylab="wind speed")
