In this workflow strings, defined in a replacement table (or dictionary) will be replaced in strings that are contained in a second data table in a recursive way. Therefor we used an recursive loop with two feedback ports.
This workflow demonstrates the usage of the "Counting Loop Start".
The workflow iterates over all numeric columns and negates the values in the column. The loop takes one column at a time, renames the column name to ANONYMOUS_COLUMN in the first rename node, changes the value in the math formula nodes and reverts the name to the original column name.
Simple workflow demonstrating the usage of the 'Generic Loop Start' node and the 'Variable Condition Loop End' node.
The flow reads a data set to be clustered (Iris data). The data file is contained in the workflow directory. The loop will use one parameter at a time, run the (parameterized) k-means algorithm, assess the clustering quality and record the values.
This workflow demonstrates how to read multiple files using a loop.
This workflow demonstrates the usage of the 'Interval Loop Start' node.
This workflow shows a solution of how to write a data table column wise to multiple csv files. Each column should be written to one separate csv file. This is a solution the a question asked in the KNIME forum:
This workflow demonstrates the usage of the "Variable Loop End".
In this workflow each file gets writen into one csv file.
