------------------------------------------------

             Summary: [R] Investigate Nodes missing from ExecPlan print out
                 Key: ARROW-17184
                 URL: https://issues.apache.org/jira/browse/ARROW-17184
             Project: Apache Arrow
          Issue Type: Bug
          Components: R
            Reporter: Dragoș Moldovan-Grünfeld


Now that we can print an ExecPlan (ARROW-15016), we can investigate unexpected outputs. With the following chunk of code:
{code:r}
mtcars %>%
  arrow_table() %>%
  select(mpg, wt, cyl) %>% 
  filter(mpg > 20) %>%
  arrange(desc(wt)) %>%
  head(3) %>%
  show_exec_plan()
#> ExecPlan with 3 nodes:
#> 2:SinkNode{}
#>   1:ProjectNode{projection=[mpg, wt, cyl]}
#>     0:SourceNode{}
{code}
 * FilterNode disappears when head/tail are involved +
 * we do not have additional information regarding the OrderBySinkNode
 * the entry point is a SourceNode and not a TableSourceNode
