2.3.4 replace_na / drop_na/—默认值处理工具 一旦明确了默认值的替代方式,replace_na和drop_na两个函数就可以通过对指定列的查询来将NA替换成需要的数值,例如,去掉所有存在默认值的观察值。表2-16中列出了函数的功能简介及使用时应注意的事项。读者可以参照帮助文档中的例子结合表2-16中的提示来自行练习这两...

将NA 替换为指定值 用法 replace_na(data, replace, ...) 参数 data DataFrame 或向量。 replace 如果data 是DataFrame ,则 replace 采用命名的值列表,其中每列有一个值需要替换缺失值。 replace 中的每个值都将转换为 data 中用作替换的列的类型。 如果data 是向量,则replace 采用单个值。该单个值替换...
Oh gosh! Every element with the factor level f1 was replacedby NA. Definitely not what we wanted. Let’s start all over with the replication of our example data: data2<-data# Replicate data If we want to convert a factor value in a data frame to a different value, we have to conver...
