添加y軸到截短barplot我有以下數據(4列和第6行數據):我已想出該R腳本,它產生了很好的截短barplot使用ggplot
w x y z
a 0.02 0.00 0.60 0.19
b 0.03 0.40 0.10 0.05
c 0.00 0.01 0.66 0.26
d 0.05 0.04 0.57 0.00
e 0.20 0.60 0.15 0.00
f 0.10 0.30 0.30 0.20
通過使用ggplot:
## importing data
plot <- read.delim("data", row.names=1)
View(plot)
### loading required packages
if (!require("Rcpp")) {
install.packages("Rcpp", repos="http://cran.rstudio.com/")
library("Rcpp")
}
library("Rcpp")
if (!require("ggplot2")) {
install.packages("ggplot2", repos="http://cran.rstudio.com/")
library("ggplot2")
}
library("ggplot2")
if (!require("grid")) {
install.packages("grid", repos="http://cran.rstudio.com/")
library("grid")
}
library("grid")
if (!require("reshape2")) {
install.packages("reshape2", repos="http://cran.rstudio.com/")
library("reshape2")
}
library(reshape2)
## transpose "plot"
plot = t(plot)
plot <- melt(plot, id.vars=2:ncol(plot))
## running ggplot
bars = ggplot(plot[!is.na(plot$value),], aes(x = Var2, y = value, fill = factor(Var1))) +
geom_bar(stat = "identity") +
scale_fill_manual(values=rainbow(length(levels(plot$Var1)))) + facet_grid(Var1~., as.table=FALSE, scale="free_y", space = "free_y") + theme_minimal() +
geom_vline(xintercept=max(as.numeric(plot$Var2))+ 0.586, size=0.3) +
theme(legend.position="none",
axis.text.x = element_text(angle = 90, colour="black", vjust = 0.4, size=8),
axis.title.x = element_blank(), axis.title.y = element_blank(), axis.ticks.y = element_blank(),
axis.line.y=element_blank(), axis.text.y=element_blank(),
strip.text.y=element_text(size = 8, colour="black", family="",angle=00, hjust = 0),
panel.grid=element_blank(),
axis.line=element_line(size = 0.3, colour = "black", linetype = "solid"),
axis.ticks.x=element_line(size = 0.3, colour = "black", linetype = "solid"),
panel.background=element_blank(), panel.margin = unit(0, "lines"))
bars
## exporting barplot "plot.png" to directory
#loading Cairo
if (!require("Cairo")) {
install.packages("Cairo", repos="http://cran.rstudio.com/")
library("Cairo")
}
library("Cairo")
#preparing exporting
png(file="plot.png",type="cairo", width = 4, height = 4.2, units = 'in',pointsize=8,res=600)
#exporting
barplot ; dev.off()
結果:
這例如「a」總分爲0.81(最大爲1),但分爲0.2(紅色),0,0.6(淺藍色)和0.19(深藍色)子列。 的事情是,我想y軸添加到每個子欄節包含此信息,這樣其他的影像中:
你知道ggplot,可以做任何選項這個?
OMG你是如此的正確,我必須刪除他們出於某種原因,然後忘了它...謝謝你注意到它! – Jaime
