编写预处理数据代码时发生R studio错误

Question

在Rstudio中编写代码时出现以下错误

Error: unexpected symbol in:
"dataset$Age = ifelse(is.na(dataset$Age),
                 ave(dataset$Age, FUN = fuction(x) mean"
>                      dataset$Age)
Error: unexpected ')' in "                     dataset$Age)"

代码如下

dataset = read.csv('Data.csv')
dataset$Age = ifelse(is.na(dataset$Age),
                 ave(dataset$Age, FUN = fuction(x) mean(x, na.rm = TRUE)),
                 dataset$Age)

任何帮助都会很棒。

Answer 1

您写的是功能而不是fu n 。

dataset = list()
dataset[["Age"]] = c(10,20,30,40,50, NA)

ifelse(is.na(dataset$Age),
       ave(dataset$Age, FUN = function(x) mean(x, na.rm = TRUE)),
       dataset$Age)

[1] 10 20 30 40 50 30
