I have the following list listaValores
我有以下清单 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))
}
which returns:
返回：

Note that you have a list. Therefore, you do not have colnamesbut names. You can edit them like this:
请注意，您有一个list. 因此，您没有colnames但是names。您可以像这样编辑它们：
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
To only edit certain entries in the list, specify an index:
要仅编辑列表中的某些条目，请指定索引：
names(l)[1] <- "new_name"
l
# $`new_name`
# [1] 123123 12123 123123
#
# $`2015`
# [1] 123123 12123 123123
If you'd like to know more about the different data types in R, I can recommend Hadley Wickham's summary.
