Example 4: repeat-Loop Through Columns of Data Frame Similar to while-loops, we can also use arepeat-loopto loop over the variables of a data frame. Again, we have to replicate our data… data4<-data# Replicate example data …and we have to specify a running index: i<-1# Create ru...
PySpark provides map(), mapPartitions() to loop/iterate through rows in RDD/DataFrame to perform the complex transformations, and these two return the
Using theiterrows()function provides yet another approach to loop through each row of a DataFrame to add new rows. The function returns an iterator resulting an index and row data as pairs. This method is useful when you need to consider the index while manipulating rows. Our initial DataFrame...

7a). In the loop extrusion model, this would require the passage of extruded loops through the heterochromatic region, suggesting that heterochromatic regions are traversable by cohesin. To test whether the loop extrusion machinery can traverse B4 domains, we turned to polymer simulations of loop ...
