library(mrgmisc) # for binning and other functions
library(ggplot2) #plotting
library(purrr) # dataset to handle lists
suppressMessages(suppressWarnings(library(dplyr)))Messy plot can’t see individuals well
ggplot(dat, aes(x = Time, y = Conc, group= ID)) +
geom_line() +
facet_wrap(~ID, scales= "free")
What we’d like to be able to do is split up into ‘bins’ of specified numbers of individuals to then plot out multiple plots
# this will automatically create a column of bins such that the
# specified number of individuals is in each bin, in this case
# 9 ids per bin
# split the original dataset into subdatasets corresponding to each bin (list of dataframes)
split_dat <- dat %>%
mutate(PLOTS = ids_per_plot(ID, 4)) %>% # default is 9 per subplot
split(.[["PLOTS"]])To handle plotting each subdataframe, you need to wrap your normal ggplot into a function. You will then apply this function with map to each subdataframe. So in this case it is just like a normal plot, but wrapped up in a function, which takes 1 argument (the dataframe) and outputs the plot
p_conc_time <- function(df) {
ggplot(df, aes(x = Time, y = Conc, group= ID)) +
geom_line() +
facet_wrap(~ID, scales= "free")
}To apply the above function we use map from purrr
