I am currently working on analyzing DNA methylation data that I obtained from the EPIC array V2. I am using the detectionP function (I presume this function is from minfi package) to calculate the detection p-values.

Here's a snippet of my code:

> # calculate the detection p-values
> detP <- detectionP(RGset)

Warning messages:
1: useNames = NA is deprecated. Instead, specify either useNames = TRUE or useNames = TRUE. 
2: useNames = NA is deprecated. Instead, specify either useNames = TRUE or useNames = TRUE. 
3: useNames = NA is deprecated. Instead, specify either useNames = TRUE or useNames = TRUE. 
4: useNames = NA is deprecated. Instead, specify either useNames = TRUE or useNames = TRUE.

When I run this code, I get the following warning as mentioned above:

Could you please guide me on how to correct this issue? Is it an issue within the package's warning system or is there something that I need to modify in my code?

Any guidance or help would be appreciated

It's fine. Probably same underlying issue (basically) as scran ScoreMarkers throws a warning -- pro-tip: please google the exact error/warning before making a post. In most cases you find an answer that way.
