在绘制列标题时,有没有一种方法可以将文本拆分成两行?
x <- runif(n = 15, min = 1, 10)
y <- runif(n = 15, min = 1, 10)
z <- runif(n = 15, min = 1, 10)
w <- runif(n = 15, min = 1, 10)
k <- runif(n = 15, min = 1, 10)
df_exemplo <- data.frame(x, y, z, w, k)
colnames(df_exemplo) <- c("Previsto ARIMA", "Previsto Holtwinters", "Observado", "Erro ARIMA (%)", "Erro Holtwinters (%)")
示例:
