Merge(., by="peakco" ) %>%Ī.opening,įile = paste0("~/Downloads/",i, ".opening.bed"),įile = "~/Downloads/"+ i + ".",įor loops in most languages can be done in a variety of ways. fdr5, .fdr10, .fdr20? Also is there a way to make the write.table function work so that it exports files with the fdr5, fdr10, fdr20 in the name? fdr.nums = c("5","10","20") A loop is a control statement that allows multiple executions of a statement or a set of statements. Loops come in the class of the most fundamental and strong programming concepts. In addition, you may want to read the other R programming tutorials of my homepage.

How do I make it run 3 times with different values and then produce 3 different datasets with names like. Loops in R (for, while, repeat) In R programming, we require a control structure to run a block of code multiple times. In the video, I’m explaining how top loop and repeat the estimation of multiple regression models using the R programming syntax of this tutorial in RStudio. I am trying to create a for loop that runs the test multiple times with different FDR values (5,10,20). The idea of the for loop is that you are stepping through a sequence, one at a time, and performing an action at each step along the way.This is probably a really quick/simple fix but I am a Noob to R programming/programming in general. Rather than iterating over a numeric progression. Unlike in R, the loop is always interpreted as an upward counting loop. When you know how many times you want to repeat an action, a for loop is a good option. The for statement in R is a bit different from what you usually use in other programming languages. The bounds in a for loop must be integers. Within the inner loop, the code would display a message box each time with the value of the LCounter1-LCounter2. In this example, the outer FOR loop would loop 4 times (starting at 1 and ending at 4) and the inner FOR loop would loop 2 times (starting at 8 and ending at 9). Suppose you want to do several printouts of the following form: The year is year where year is equal to 2010, 2011, up to 2015. The inner FOR loop is controlled by the LCounter2 variable. Let’s get back to the conceptual meaning of a loop. If you want to take our Intermediate R for Finance course, here is the link. If you want to learn more on the concepts of vectorization in R, this is a good read.
