我创建了一个看起来像这样的数据集:
> Data
ZIP.Code Graduation.Rate Residences Tax_Payers Businesses Pot_Holes
1 60605 0.00876233 -0.43780716 -0.69756117 -0.705236816 -0.44078331
2 60607 -0.93779113 -0.62411552 0.45619155 0.429939383 -0.82886125
3 60608 -0.35352395 0.77774127 0.83458530 0.694500368 0.28789804
...
这些特征中的每一个的值都在[-1,1]
范围内缩放。我希望有一个散点图,使得x轴具有ZIP_Code
的标签,y轴对于每个缩放值具有4个标记。我怎么能在R中这样做?
将数据融合为长形式,以便将所有四个变量的数据传递给一个美学:
df_melt <- reshape2::melt(df, id.var = 'ZIP.Code')
# or
df_melt <- tidyr::gather(df, variable, value, Graduation.Rate:Pot_Holes)
df_melt
# ZIP.Code variable value
# 1 60605 Graduation.Rate 0.00876233
# 2 60607 Graduation.Rate -0.93779113
# 3 60608 Graduation.Rate -0.35352395
# 4 60605 Residences -0.43780716
# 5 60607 Residences -0.62411552
# 6 60608 Residences 0.77774127
# 7 60605 Tax_Payers -0.69756117
# 8 60607 Tax_Payers 0.45619155
# 9 60608 Tax_Payers 0.83458530
# 10 60605 Businesses -0.70523682
# 11 60607 Businesses 0.42993938
# 12 60608 Businesses 0.69450037
# 13 60605 Pot_Holes -0.44078331
# 14 60607 Pot_Holes -0.82886125
# 15 60608 Pot_Holes 0.28789804
ggplot2
ggplot(df_melt, aes(x = factor(ZIP.Code), y = value, colour = variable)) +
geom_point() + xlab('ZIP Code')
with(df_melt, plot(ZIP.Code, value, col = variable, pch = 19))
请注意,它有一些问题,包括排列相当差的x轴。如果您真的附加到基本图形,按摩代码可以修复它们。
