Set size of pie diameter

[JDuffyEx]

Hello,

Thanks for the tool, is there a way to scale the radius of the pies so they are proportional to a value for each location e.g. rpkm?

Cheers!

Hi @JDuffyEx,

I received your issue via email but there is no text in your post since your edit. Please can you re-post your issue, otherwise I will close this.

Thanks,
Tom

Update:
I can see your post again. I will try and implement this functionality but it may take me some time.

Hi @JDuffyEx,

I think I have implemented the feature you described. The pie_size argument now accepts a single value or a vector of values the same length as the number of sites. This allows users to plot pies of different sizes for different sites.

Example:

library(mapmixture)

# Admixture Format 1
file <- system.file("extdata", "admixture1.csv", package = "mapmixture")
admixture1 <- read.csv(file)

# Coordinates Format
file <- system.file("extdata", "coordinates.csv", package = "mapmixture")
coordinates <- read.csv(file)

# Plot using a single value
mapmixture(admixture1, coordinates, pie_size = 1)
mapmixture(admixture1, coordinates, pie_size = 1, crs = 3035)

# Plot using a vector of values
pie_radius <- c(1,2,1,3,1,1,1,1,1,1)
mapmixture(admixture1, coordinates, pie_size = pie_radius)
mapmixture(admixture1, coordinates, pie_size = pie_radius, crs = 3035)

You will also get an informative warning if you input an incorrect number of pie radius values:

> mapmixture(admixture1, coordinates, pie_size = c(1,2,3), crs = 3035)
Error in mapmixture(admixture1, coordinates, pie_size = c(1, 2, 3), crs = 3035) : 
  Invalid input: pie_size vector must be of length 1 or the same length as the number of sites

Please let me know if this is OK. It will be part of the next release of mapmixture to CRAN. For now, to use this feature download the latest development version from GitHub:

# install.packages("devtools")
devtools::install_github("Tom-Jenkins/mapmixture")
