我想要做這樣的事情圖形，與R：

enter image description here

我讀了CSV，但我不知道我必須做些什麼才能將CSV中的數據分組並將這些數據放入barplot中。

此外，我需要添加品種到每個ID組。

這是我的代碼：

path <- "./" 

cosechas <- read.csv(paste(path, "test.csv", sep="/"),header=T) 

cosechas$Kgms <- as.numeric(cosechas$Kgms) 



fi <- c(cosechas$Kgms) 
names(fi) <- levels(cosechas$Category) 


png(paste(path, "cosechas.png", sep="/")) 

barplot(fi, ylab="Kg", xlab="Categoria") 
dev.off()

在此先感謝。

是不是[任何關於分組的條形圖的回答]（http://stackoverflow.com/search?q= [r] +分組的+ barplot）有幫助嗎？如果您有特定的問題，請[顯示您嘗試過的代碼並描述爲什麼它不起作用]（http://stackoverflow.com/help/on-topic）。乾杯。 – Henrik

好的！抱歉。我的代碼。編輯 – ManuParra

我看不到代碼..... –

如果您希望全部爲單色，則可以將「填充」更改爲「組」。

df <- read.csv('your/file.csv') 
library(ggplot2) 
ggplot(df, aes(x = ID, y = Kgrs, fill = Category)) + 
geom_bar(stat = 'identity', position='dodge')

如果我把每個ID的品種？ – ManuParra

查看「交互」功能（'？interaction'）。你可能需要'x =交互（ID，Variety）'。 – colcarroll
