The loop Handle up front should really help proper reasoning about what is occurring Within the loop. Modifying loop counters in equally the iteration-expression and In the body of the loop is often a perennial source of surprises and bugs.
In this manual all commands are offered in code boxes, exactly where the R code is printed in black, the remark textual content in blue plus the output generated by R in eco-friendly. All feedback/explanations start with the standard comment indicator '#' to forestall them from remaining interpreted by R as instructions.
