最常见的数据清洗步骤包括删除重复数据、替换缺失数据、转换数据类型和筛选数据等。 例如,下面的代码可以删除dataframe中重复的行: ``` unique_df <- unique(df) ``` 1. 2. 3. 4. 5. 2. 数据探索 数据探索是R源码数据分析的重要步骤之一。在这个步骤中,我们可以使用R语言中的各种函数和包来探索数据的分布...

Thetapply()function applies a function to a set of values that are grouped by some factor. This is pretty much the same as theaggregate()function, but the output format is different. As a demo, let’s first set up a dataframe:
Because another common text source is a data frame, there is a Source function calledDataframeSource(). TheDataframeSource()function treats the entire row as a complete document, so be careful not to pick up non-text data like customer IDs when sourcing a document this way. ...
