Off topic:package circlize: How to add padding to circos.genomicInitialize()?

Question

[bsmith030465]

Hi,

I wanted to use the 'circlize' package to make some genomic graphs. I wanted to follow the example given in the vignette/manual (https://jokergoo.github.io/circlize_book/book/initialize-genomic-plot.html - section 9.3)

tp_family = readRDS(system.file(package = "circlize", "extdata", "tp_family_df.rds"))

head(tp_family)

##   gene   start     end        transcript exon
## 1 TP53 7565097 7565332 ENST00000413465.2    7
## 2 TP53 7577499 7577608 ENST00000413465.2    6

circos.genomicInitialize(tp_family)

My questions:

1. How can I modify the sample data to incude the 5' and 3' UTRs?
2. How can I extend the x range for the gene such that the plot shows +/- 2kbp from the 5' and 3' ends?

thanks for your help!
