函数内部的列操作将数据帧变为空或意外的值
我有一个运行良好的函数,我想通过删除其中一列并使用这些命令将另一列中的NA值转换为1来清理输出:函数内部的列操作将数据帧变为空或意外的值
df$PlateIden <- NULL df$PlateNum[is.na(df$PlateNum)] <- 1
,当我直接使用我的功能之外的数据帧,但是当我在函数中使用他们我的数据框变成要么是“空”或“1”,如果任一功能的值。这些工作用过的。
这里是我的全部功能:
cleanup_safe <- function(df,addproject,adduser){ colnames(df) <- "FileName"
df$RunDate <- str_match(df$FileName, "^[a-zA-Z ]*(\\d+)")[,2]
df$RunDate <- ymd(df$RunDate)
df$PlateNum <- str_match(df$FileName, "(?<=Plate|plate)[_ ]?(\\d)")[,2]
df$PlateIden <- str_match(df$FileName, "(?<=Plate|plate)[_ ]?\\d*[_ ]?([a-zA-Z])")[,2]
df$User <- "adduser"
df$Project <- "addproject"
df <- df[!duplicated(df[,c("User","Project","RunDate","PlateNum")]),]
df <- within(df, ID <- cumsum(!duplicated(df[c("User","Project","RunDate")])))
df$PlateIden <- NULL
df$PlateNum[is.na(df$PlateNum)] <- 1
}
下面是测试数据集

回答:
与
setDT(df) df[is.na(PlateNum), PlateNum := 1].
所以更换df$PlateNum[is.na(df$PlateNum)] <- 1
,你的整个会是这样的:
使用data.table
library(data.table) test <- c("20160801, Optimization, gp70_B.CaseA_V1_V2 Coupling Testing, Plate 1a, IgG-Biot, MAF.srbx",
