Hi all... I assume there are a host of GGplot2 users out there. I have circular plot - polar plot code questions I needed to create circular – polar plots of reproductive status for bats. I found a great sample of how to do this here: https://stackoverflow.com/questions/41081376/how-to-create-a-circular-plot-showing-monthly-presence-or-absence-using-radial-p
I modified the sample code to meet the 3 data elements I am using the "raw data" table below with T=testes enlarge, P= Pregnant and L= Lactating. library(data.table) m <- fread("id T month P L 1 0 1 0 0 2 0 2 0 0 3 0 3 0 0 4 1 4 0 0 5 1 5 1 0 6 1 6 1 1 7 0 7 1 1 8 0 8 1 1 9 0 9 0 1 10 0 10 0 0 11 0 11 0 0 12 0 12 0 0") # reshape from wide to long (as preferred by ggplot) ml <- melt(m, measure.vars = c("T", "P", "L")) # create factors to ensure desired order ml[, variable := factor(variable, levels = c("T", "P","L"))] ml[, fct_month := factor(month, levels = 1:12, labels = month.abb)] library(ggplot2) ggplot(ml[value != 0], aes(x = fct_month, y = variable, group = variable, colour = variable)) + geom_line(size = 3) + scale_y_discrete(expand = c(0, 1), breaks = NULL) + xlim(month.abb) + coord_polar() + theme_bw() + xlab(NULL) + ylab(NULL) This is creating a plot more or less as needed. 4 questions: 1 Do I even need the ID field? Seems not useful. 2 I assume the melt step can be avoided if my data is "Tidy" and long format at the start, correct? 3 How can I increase the weight of the month lines and labels 4 Where can I add color choices for the 3 variables in the plot? Simply adding an HTML color number to the “colour=variable” then plots the data and labeling one value as that color. Tnx all. The list is always educational on a daily basis.
