R - 熱圖，設置ColSideColors

我可以使用palette()沿着熱圖的行和列設置顏色標籤嗎？我做一個隨機4x4矩陣，繪製熱圖，並嘗試設置側面顏色：R - 熱圖，設置ColSideColors

m <- matrix(rnorm(16), 4, 4) 
c <- c(1,1,2,2) 
heatmap(m,ColSideColors=c)

，我得到的錯誤：

"Error in heatmap(m, ColSideColors = c) : 
    'ColSideColors' must be a character vector of length ncol(x)"

您在錯誤消息中有答案。查看'class（c）'的結果。並且請避免使用'c'作爲變量的名稱。 – 2015-04-07 08:27:54

從?heatmap：

ColSideColors (optional) character vector of length ncol(x) containing the color names for a horizontal side bar that may be used to annotate the columns of x.

set.seed(42) 
m <- matrix(rnorm(16), 4, 4) 
xsidecols <- c("#cdcd0d", "#0dcdcd", "#cd0dcd", "grey") 
heatmap(m, ColSideColors = xsidecols)
