2 dataframes in single dplyr pipeline

Question

Hi, Is it possible to use 2 dataframe/datasets in a pipelined statements? I need data from first dataframe and pass it to dataframe2 and fetch result.

Answer 1

You can use 2 different data frames in one pipeline but not together i,e

You can do this - >

dataframe1 %>% filter(dataframe1$var condition,dataframe2$var condition) %>% ................

But not this ->

dataframe1 %>% filter(var condition) %>% dataframe2 %>% filter(var condition) %>% ................

You can access secondary or multiple data frames within the pipeline of one data frame with its dataframe$variable_name.

Hope it helps.
