R语言:如何设置ylim?

问题描述

我正在尝试以最大9.70和最小-58.9绘制数据.

I am trying to plot data with maximum 9.70 and minimum -58.9.

我编码:

plot(BriannaJan[,3,i], type = "line", col="black", 
     main = "Brianna January Trend", xlab = "days", ylab="Temperature", 
     ylim = -60:10)

但是我得到了错误:

Error in plot.window(...) : invalid 'ylim' value

如何设置ylim? y值范围必须介于-60到10之间.

How can I set ylim? y value range has to be from -60 to 10.

推荐答案

-60:10生成一个从-60到10的序列，因为ylim是一个最小值和最大值(语法为c(min, max) )而不是序列，请尝试以下操作:

-60:10 generates a sequence from -60 to 10, what you need as the ylim is a min and max value (with syntax c(min, max)) instead of a sequence, try this:

ylim=c(-60,10)
