我得到这个错误:GGPLOT2错误:美学必须是一个长度或相同长度的dataProblems:颜色,字母
Error: Aesthetics must either be length one, or the same length as the dataProblems:colors, letters
,当我使用ggplot与数据帧Z
如下所示:
Z <- data.frame("Name"=c("A","G","C","T","T","T","AG","AG","GC","GC","CT","CT","AT","AT","CT","CT"),
"Track"=c(0,0,0,0,0,0,1,1,1,1,1,1,1,1,1,1),
"Position"=c(1,1,1,1,1,1,1,2,2,3,3,4,9,10,12,13))
Z[1:16] # Small dummy sample
# Name Track Position
# 1 A 0 1
# 2 G 0 1
# 3 C 0 1
# 4 T 0 1
# 5 T 0 1
# 6 T 0 1
# 7 AG 1 1
# 8 AG 1 2
# 9 GC 1 2
# 10 GC 1 3
# 11 CT 1 3
# 12 CT 1 4
# 13 AT 1 9
# 14 AT 1 10
# 15 CT 1 12
# 16 CT 1 13
在这里,我创建一个调色板后适用于geom_raster
# Create color palette
x <- length(levels(Z$Name))
x.colors <- hcl(h=seq(15,375,length=(x+1)),l=65,c=100)[1:x]
x.colors[1:4] <- c("blue","red","green","yellow")
colors <- factor(x.colors)
letters <- factor(levels(Z$Name))
my_fill <- x.colors
此代码尝试绘制所有内容:
# Plot
ggplot(NULL) +
aes(x = Z$Track,
y = Z$Position,
fill = colors,
label = letters) +
geom_raster() +
geom_text() +
scale_fill_manual(values=my_fill)
'aes'应该是里面'ggplot()'。 – 2015-07-22 07:07:00
在'aes'里面用'fill = Z $ Name'和'label = Z $ Name'试试。看起来很奇怪,但在Track/Position 0/1,1/2和1/3处有重复。 –
当我这样做时,我遇到了另一个错误'错误:ggplot2不知道如何处理类的数据uneval' @帕斯卡尔 – ALKI
