[Bioc-devel] DataFrame conversion

[Daniel Schulz]

Dear all,

I am maintaining the imcRtools package. Since Monday we have a build error on the development version. Most of the errors are attributed to test functions which fail now and can be attributed to the below problem.
It seems that currently with R 4.4 and Bioconductor 3.19 the following code will throw a warning which it did not in R4.3/Bioconductor 3.18:


> x <- S4Vectors::DataFrame(x = c(1,2,4),y=c("A","B","C"))

> as.data.frame(x)

  x y

1 1 A

2 2 B

3 4 C

Warning message:

In as.data.frame.numeric(col, optional = optional) :

  Direct call of 'as.data.frame.numeric()' is deprecated.  Use 'as.data.frame.vector()' or 'as.data.frame()' instead

I don't really understand what changed in R4.4, Bioconductor 3.19 or S4Vectors that we get these warnings. However, many functions, specifically test functions in our package fail now due to the warning.
Any advice on how to handle this?
Best,
Daniel
