installation errors

Hi，
The following error is reported while installing aPEAR:

267:   edges %>%
268:     .[ , xStart := lapply(from, \
                                     ^

Can it be solved?
Thanks

I also encountered the same error in R-4.0.3:

Hi, I'm not sure how helpful this will be since I haven't encountered this issue before, but I wanted to mention that there are multiple versions of aPEAR available. The CRAN version (v1.0.0) is different from the GitHub version (v1.0) and they have different functionalities. You might want to try installing the CRAN version to see if it resolves the issue.
