按列中的峰值时间对timeseries热图中的行进行分组
我正在设计一个细胞周期时间序列中最受高度调控的基因的热图按列中的峰值时间对timeseries热图中的行进行分组,r,ggplot2,R,Ggplot2,我正在设计一个细胞周期时间序列中最受高度调控的基因的热图 example <- read.csv("example.csv", header = T) example.m <- melt(example) (e <- ggplot(example.m, aes(variable, Gene_ID)) + geom_tile(aes(fill = value), colour = "white") + scale_fill_gradient(low = "white", h
example <- read.csv("example.csv", header = T)
example.m <- melt(example)
(e <- ggplot(example.m, aes(variable, Gene_ID)) + geom_tile(aes(fill =
value), colour = "white") + scale_fill_gradient(low = "white", high =
"steelblue"))
example您应该可以添加这一行来设置Y轴的顺序example.m$Gene\u ID Close,我希望按它们的窥视位置来排序。如果表达式在0处是最高的,它将与在0处有最高表达式的其他表达式一起分组,依此类推。我不相信我的排列函数能做到这一点,有什么建议吗?你正在把所有最高的零分组合在一起,所以我真的不明白你想要什么。您不能将最高值为0的数据分组在一起,也不能同时将最高值为30的数据分组在一起。
order <- arrange(example, X0, X30, X60, X90, X120, X150, X180, X210, X240)
example <- data.frame(Gene_ID = paste0("TTHERM_", 1:9),
X0 = round(runif(9, min =0, max = 4.4999),0),
X30 = round(runif(9, min =0, max = 4.4999),0),
X60 = round(runif(9, min =0, max = 4.4999),0),
X90 = round(runif(9, min =0, max = 4.4999),0),
X120 = round(runif(9, min =0, max = 4.4999),0),
X150 = round(runif(9, min =0, max = 4.4999),0),
X180 = round(runif(9, min =0, max = 4.4999),0),
X210 = round(runif(9, min =0, max = 4.4999),0),
X240 = round(runif(9, min =0, max = 4.4999),0))
