[英]Heatmap returning error: 'x' must be a numeric matrix, but x is a numeric matrix
我正在嘗試創建六個站點上物種豐富度的熱圖。 我有一個站點與物種,數字豐度數據的矩陣。
但是,當我運行代碼時,R返回一個錯誤,表明我的矩陣是非數字的。 誰能解決這個問題? 我感到難過。
導出的數據框鏈接: log_mean_wide
工作方式:
lrc <- rainbow(nrow(log_mean_wide), start = 0, end = .3)
lcc <- rainbow(ncol(log_mean_wide), start = 0, end = .3)
logmap <- heatmap(log_mean_wide, col = cm.colors(256), scale = "column",
RowSideColors = lrc, ColSideColors = lcc, margins = c(5, 10),
xlab = "species", ylab = "Site",
main = "heatmap(<Auckland Council MCI data 1999, habitat:bank>, ..., scale = \"column\")")
錯誤消息:熱圖錯誤(log_mean_wide,Rowv = NA,Colv = NA,col = cm.colors(256),:'x'必須是數字矩陣
log_heatmap <- heatmap(log_mean_wide, Rowv=NA, Colv=NA, col = cm.colors(256), scale="column", margins=c(5,10)) #same error
is.numeric(log_mean_wide) #[1] FALSE
is.character(log_mean_wide) #[1] FALSE
is.factor(log_mean_wide) #[1] FALSE
is.logical(log_mean_wide) #[1] FALSE
is.integer(log_mean_wide) #[1] FALSE
?!?!
dims <- dim(log_mean_wide)
log_mean_matrix <- as.numeric(log_mean_wide)
dim(log_mean_matrix) <- dims
錯誤:(列表)對象無法強制輸入“ double”類型
str(log_mean_wide)將物種顯示為數字,將站點顯示為字符-為什么這不起作用?
storage.mode(log_mean_wide) <- "numeric"
storage.mode(log_mean_wide)<-“ numeric”:(list)對象中的錯誤無法強制輸入'double'類型
有兩個問題:
log_mean_wide$Site
是非數字的。 heatmap
僅接受matrix
作為輸入數據(不接受data.frame
)。 要解決這些問題,您可以執行以下操作(請注意,熱圖中有很多混亂情況):
# Store Site information as rownames
df <- log_mean_wide;
rownames(df) <- log_mean_wide[, 1];
# Remove non-numeric column
df <- df[, -1];
# Use as.matrix to convert data.frame to matrix
logmap <- heatmap(
as.matrix(df),
col = cm.colors(256),
scale = "column",
margins = c(5, 10),
xlab = "species", ylab = "Site",
main = "heatmap(<Auckland Council MCI data 1999, habitat:bank>, ..., scale = \"column\")")
