arrowheads option doesn't work #72

Hello, Kevin!

There are some enhancements in the new EnhancedVolcano, but some things are changed and even broken definitely. How can I control the WIDTH of arrow heads? Previous version generated MUCH more pleasant-looking arrows. Moreover, I cannot turn off arrow heads at all: I've tried arrowheads=FALSE (as in the example at github): Error in EnhancedVolcano(res, lab = res$symbol, x = "log2FoldChange", : unused argument (arrowheads = FALSE) And I've tried "new style" arrowHeads=FALSE with the same result: Error in EnhancedVolcano(res, lab = res$symbol, x = "log2FoldChange", : unused argument (arrowHeads = FALSE)

Hi, you need to upgrade your version of R to 4.0.x in order to avail of this new functionality. As you are using R 3.6.3, install.packages() and BiocManager::install()will automatically download an older version of EnhancedVolcano.

Note that some of the labeling via arrows / connectors is controlled via ggrepel, which is used by EnhancedVolcano.
