我想生成一個顯示x軸日期的繪圖(Base R)。使用plot在x軸上設置日期
這是我到目前爲止的代碼:
plot(dr[[ncol(dr)]][-(length(dr[[ncol(dr)]]))], type = 'l', main =
paste("Title - ", colnames(dr[ncol(dr)])), xlab = "", ylab = "",
xaxt = 'n', col = "red", lwd = 2, cex.main = 2, ylim = c(0,0.5))
title(xlab = "Period", line=0.5, cex.lab = 1.5)
如何把在x軸上的日期?
這裏的情節:
這是我的變量日期:
