《数据挖掘：R语言实战》P234中，UCI数据库中白酒品质研究数据集4898个样本下载问题

• UCI数据框中白酒品质研究数据集4898个样本下载问题

• 由于本书的作者给出的数据集只有178条信息，且无法对“wine$quality”进行分类
• 经过查询，现找到数据，分享给大家，下载“winequality-white.csv”数据即可，链接如下：http://archive.ics.uci.edu/ml/machine-learning-databases/wine-quality/

• 对应数据处理代码如下：

###应用案例###
library(randomForest)
wine=read.csv("winequality-white.csv",head=TRUE,sep=";")
View(wine)

# 更改变量名
names(wine)=c("fixed acidity","volatile acidity","citric acid","residual sugar","chlorides","free sulfur dioxide","total sulfur dioxide","density","PH","sulphates","alcohol","quality")

# 显示
View(wine)
# 获取概括信息
summary (wine)   

• 学习愉快！
