Thanks again Joris – you’ve been very helpful J, From: Joris FA Meys [via x <- rnorm(1:10) Using IRanges, you should use findOverlaps or mergeByOverlaps instead of countOverlaps. >. That solves it. I've had a look at the conditions in base and I can't get the ones to work I've looked at but it is all new to me. See that blog entry for... Change the panel.margin argument to panel.margin = unit(c(-0.5,0-0.5,0), "lines").

One thing I was missing, which breaking out of for loop when running a function inside a for loop in R makes clear, is this:. $'\r' is a representation of the carriage return character (CR) that is part of traditional DOS and Windows line endings (CR LF), but which is absent in traditional Unix-style line endings (LF). If you use the R and W switches with an argument of 0, then Robocopy should just skip errors and continue . A single logical value between parentheses (or an expression that leads to a single logical value) A block of code between braces that has to be executed when the logical value is TRUE. ; Go to the path and delete the package … The value is inspected and deferred to either file= (if no \n present), text= (if at least one \n is present) or cmd= (if no \n is present, at least one space is present, and it isn't a file name).

R prefers to use i rather than j. Aslo note that complex is different than as.complex and the latter is used for conversion. The function author signals conditions with functions like stop() (for errors), warning() (for warnings), and message() (for messages), then the function user can handle them with … ; You need to send some signal or flag (e.g., Voldemort = TRUE) from inside your function (in my case tryCatch) to the outside.

For the example, I fit a linear mixed effects model using lmer (just because I happen to be working with mixed models, and they throw back convergence errors more often than GLMs), then used the update function to challenge it with random draws from my dataframe. Can someone help me with this? I'm sorry, I don't understand your problem to the detail so my suggestion may be waaay off, but how's this?

It's often the case that I want to write an R script that loops over multiple datasets, or different subsets of a large dataset, running the same procedure over them: generating plots, or fitting a model, perhaps.

When starting a new post, to receive a quicker and more targeted answer, Please include a sample file in the initial post. An if statement in R consists of three elements: The keyword if. Here is the result: ... A better approach would be to read the files into a list of data.frames, instead of one data.frame object per file. The test script at the end of this post demonstrates how messages and errors can be generated within a function and then trapped and processed by a calling function, potentially generating new errors that could be passed upstream. Then use the function step to re … I think this code should produce the plot you want. PLEASE do read the posting guide http://www.R-project.org/posting-guide.html I would create a list of all your matrices using mget and ls (and some regex expression according to the names of your matrices) and then modify them all at once using lapply and colnames<- and rownames<- replacement functions. … Assuming files is the vector of file names (as you imply above): import <- lapply(files, read.csv, header=FALSE) Then if you want to operate on each data.frame in the list... r,function,optimization,mathematical-optimization. > from which I would recognise the warning in ff and not those in ee, saving The RStudio 1.2 release comes with a new rendering engine based on the same technology as Chromium, and attempts to make use of hardware accelerated rendering when possible.

Juliet Hannah: Here are two things to try.First check the data. I'd like to set a condition which says something like "if error, then print NAs" rather than the loop breaking, but I don't know how to say "if error". I get multiple such errors on the same 1 MB file and it may take 10-20 min to proceed to the next file, which may or may not give similar errors. Thanks in advance . Click here to reveal answer. A single character string. I want it to look in O2 and if it is TRUE, return the value from A2. skip_on_covr() skips when covr is running (using the R_COVR env var).

In your case, you're getting the values 2 and 4 and then trying to index your vector again using its own values. Claim Now. y <- letters[1:10] However, to those accustomed to working with missing values in other packages, the way in which R handles missing values may require a shift in thinking. R: recursive function to give groups of consecutive numbers, Keep the second occurrence in a column in R. [on hold], ggplot2 & facet_wrap - eliminate vertical distance between facets, R: Using the “names” function on a dataset created within a loop, Store every value in a sequence except some values. If the expression is FALSE, then it will check the Next one (Else If Boolean expression) and so on. When we run the code above, the output is the number 5.
