R 重命名列表项
我有以下列表R 重命名列表项,r,list,data-structures,rename,R,List,Data Structures,Rename,我有以下列表listaValores listaValores <- c() for(valores in 1:numRepeticion){ listaValores <- c(listaValores, readWorksheetFromFile(file = file.read, sheet = sheet.read, startRow = startR
listaValores
listaValores <- c()
for(valores in 1:numRepeticion){
listaValores <- c(listaValores, readWorksheetFromFile(file = file.read,
sheet = sheet.read,
startRow = startRow.read+(12*(valores-1)),
startCol = startCol.read[i],
endRow = startRow.read+((12*valores)-1) ,
endCol = startCol.read[i], header = FALSE))
}
如何将其元素重命名为
2014
,2015
,2016
?请注意,您有一个列表。因此,您没有colnames
,而是名称
。您可以这样编辑它们:
l <- list(col1 = c(123123, 12123, 123123), col1 = c(123123, 12123, 123123))
l
# $col1
# [1] 123123 12123 123123
#
# $col1
# [1] 123123 12123 123123
names(l)
# [1] "col1" "col1"
names(l) <- c("2014", "2015")
l
# $`2014`
# [1] 123123 12123 123123
#
# $`2015`
# [1] 123123 12123 123123
l如果您想使用列表名而不是索引,这是可行的
