我想将某些列更改为整数（从表的4列更改为最后一个列）。我该怎么办？
我已经尝试过
databianca %>%
mutate_if(is.factor, ~as.integer(as.character(.)))
和
databianca %>%
mutate_at(vars(columbia:escrita.POS), ~as.integer(as.character(.)))
同时收到这两个警告：
警告消息： 1：在（函数（...，.x = ..1，.y = ..2，。= ..1）中： 强制引入的NAs
2：在（函数（...，.x = ..1，.y = ..2，。= ..1）中： 强制引入的NAs
3：在（函数（...，.x = ..1，.y = ..2，。= ..1）中： 强制引入的NAs
4：在（函数（...，.x = ..1，.y = ..2，。= ..1）中： 强制引入的NAs
5：在（函数（...，.x = ..1，.y = ..2，。= ..1）中： 强制引入的NAs
6：在（函数（...，.x = ..1，.y = ..2，。= ..1）中： 强制引入的NAs
7：在（函数（...，.x = ..1，.y = ..2，。= ..1）中： 强制引入的NAs
8：在（函数（...，.x = ..1，.y = ..2，。= ..1）中： 强制引入的NAs
难道没有选择将从哥伦比亚到最后一列的所有列（在Matlab中我将使用4：end给出从第4列到最后一个元素的指令）作为整数吗？

答案 0 :(得分：0)
在as.integer变量上使用non-integer时会发生这种情况。
看来您的数字中包含“，”（例如：51,66），并且换行符也造成了问题，因此请先使用gsub()使因子“干净”，然后再运行as.integer()
databianca[,4:length(names(databianca))] <- apply(databianca[, 4:length(names(databianca))], 2, function(x) as.integer(gsub("[\n,]", "", x)))
这也应该起作用
databianca[,4:length(names(databianca))] <- as.integer(gsub("[\n,]", "", as.matrix(databianca[,4:length(names(databianca))])))
