今天,我们要介绍一个超实用的R函数——tidyr::replace_na()!这个函数可以轻松地将vector或dataframe中的NA值替换成我们想要的其他值。📊例如,如果你有一个character类型的vector,你可以将它中的NA替换成"Missing"或者" "。只需要这样写:replace_na(x, "Missing")。
使用replace_na函数可以对缺失值进行替换或删除操作。例如,替换缺失值为一个特定的值: library(tidyverse)df<-tibble(x=c(1:5,NA))replace_na(df,list(x=0)) 复制 输出结果: # A tibble: 6 x 1x<dbl>112233445560 可以看到,所有缺失值(NA)都被替换成了0。
