我使用data.table(版本1.10.4)来清理数据(顺便说一句,我已经安装了“reshape2”),但是我收到了这条消息:
melt_check(data,id.vars,measure.vars,variable.name,value.name)出错: 找不到功能“模式”
我多次检查过,但是没弄清楚原因。我在下面发布我的代码,任何人都可以查看它,并告诉我我错在哪里?感谢。
library(reshape2)
library(data.table)
library(readxl)
data<-read_excel("Time3Ratee.xlsx")
meltdata<-melt(data,id = 1:4, measure = patterns ("^ratee\\d+$","^RICB.peer\\d+\\.1", "^RICB.peer\\d+\\.2","^RICB.peer\\d+\\.3", "^TICB.peer\\d+\\.1", "^TICB.peer\\d+\\.2","^TICB.peer\\d+\\.3","^LE.peer\\d+\\.1", "^LE.peer\\d+\\.2","^LE.peer\\d+\\.3","^LE.peer\\d+\\.4", "^DEV.peer\\d+\\.1", "^DEV.peer\\d+\\.2","^DEV.peer\\d+\\.3"), value.name = c("ratee", "RICB.peer.1", "RICB.peer.2","RICB.peer.3", "TICB.peer.1", "TICB.peer.2","TICB.peer.3", "LE.peer.1", "LE.peer.2","LE.peer.3","LE.peer.4", "DEV.peer.1", "DEV.peer.2","DEV.peer.3"))
答案 0 :(得分:1)
(将@Franks评论转换为答案)
为了能够使用data.table::melt
,您需要使用data.table
或as.data.table()
setDT()
类
setDT(data)
否则,melt
将默认为reshape2::melt
,您将无法使用data.tables功能,例如patterns
。
