rmarkdown error “attempt to use zero-length variable name”
Putting this as an answer for visibility: this happens if you try to run by selecting all in the Rmd and pressing enter like you would with a normal R script. RStudio tries to run this all as R code, including the markdown parts, leading to the errors you saw. You can avoid this by … Read more
Longer object length is not a multiple of shorter object length?
Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they’re the same length if they differ, which means you might be performing operations on mismatched data. In this case you have an obvious flaw in that your subtracting aggregated data from … Read more

Principal Components Analysis:Error in colMeans(x, na.rm = TRUE) : ‘x’ must be numeric
You can convert a character vector to numeric values by going via factor. Then each unique value gets a unique integer code. In this example, there’s four values so the numbers are 1 to 4, in alphabetical order, I think: You can then run prcomp: Whether this makes sense for your application is up to you. Maybe … Read more

Error in file(file, “rt”) : invalid ‘description’ argument in complete.cases program
It’s hard to tell without a completely reproducible example, but I suspect your problem is this line: id here is a vector, so path becomes a vector of character strings, and when you call read.csv you’re passing it all the paths at once instead of just one. Try changing the above line to and see if that works.
“Error: Mapping should be created with `aes()` or `aes_()`.”
I’m trying to build a simple histogram with ggplot2 package in R. I’m loading my data from a csv file and putting 2 of the columns together in a data frame, like this: sp is recognised as a factor of 23 levels (my number of lines) and cov as 23 numbers. Then, to build the … Read more
