问题描述
我尝试在R中导入包含邮政编码信息的CSV,当我需要它作为字符时,它会解释为数字。
I am trying to import a CSV in R which has ZIP code information which R is interpreting as numeric when I need it to remain as character.
data = read.csv("zipCodeInformation.csv", stringsAsFactor = FALSE)
数据格式如下:
Lower.Zip, Upper.Zip, Zone
004, 005, Zone.8
006, 007, Zone.45
009, , Zone.45
010, 089, Zone.8
100, 339, Zone.8
现在发生了什么,R将前2列解释为数字,并将其转换为以下形式:
What happens right now is R interprets the first 2 columns as numeric and turns them into the following:
Lower.Zip, Upper.Zip, Zone
4, 5, Zone.8
6, 7, Zone.45
9, , Zone.45
10, 89, Zone.8
100, 339, Zone.8
推荐答案
使用 colClasses
参数 read.csv
。
Data <- read.csv(text="Lower.Zip, Upper.Zip, Zone
004, 005, Zone.8
006, 007, Zone.45
009, , Zone.45
010, 089, Zone.8
100, 339, Zone.8",
colClasses=rep("character",3)) # you may want to add strip.white=TRUE
