Make a plot of coefficient of variation over time

plot_cv_data() enables you to save a plot of the coefficient of variation in evoked current amplitudes over time.

Usage

plot_cv_data(
  data,
  plot_treatment = "Control",
  plot_category,
  treatment_colour_theme,
  included_sexes = "both",
  male_label = "Male",
  female_label = "Female",
  theme_options,
  save_plot_png = "no",
  ggplot_theme = patchclampplotteR_theme()
)

Arguments

data

A dataframe of the pruned current data for all cells. This is the third dataframe in the list generated from make_pruned_EPSC_data().

plot_treatment

A character value specifying the treatment you would like to plot (e.g. "Control"). plot_treatment represents antagonists that were present on the brain slice, or the animals were fasted, etc.

plot_category

A numeric value specifying the category, which can be used to differentiate different protocol types. In the sample dataset for this package, plot_category == 2 represents experiments where insulin was applied continuously after a 5-minute baseline period.

treatment_colour_theme

A dataframe containing treatment names and their associated colours as hex values. See sample_treatment_names_and_colours for an example of what this dataframe should look like.

included_sexes

A character value ("both", "male" or "female"). Useful if you want to have a plot with data from one sex only. Defaults to "both". If you choose a single sex, the resulting plot will have "-males-only" or "-females-only" in the file name. WARNING!! If you choose "male" or "female", you MUST ensure that the t_test_df contains data that has been filtered to only include one sex. Otherwise, the significance stars will represent both sexes and it will be inaccurate.

male_label

A character value used to describe how males are encoded in the sex column of the dataframe used in data. This MUST match the value for male data in the sex column, and it must be consistent across data sheets. Defaults to "Male".

female_label

A character value used to describe how females are encoded in the sex column of the dataframe used in data. This MUST match the value for female data in the sex column, and it must be consistent across data sheets. This must be consistent in all data sheets. Defaults to "Female".

theme_options

A dataframe containing theme options. See sample_theme_options for an example of what this dataframe should look like.

save_plot_png

A character ("yes" or "no"). If "yes", the plot will be saved as a .png using ggsave. The filepath depends on the current type, but they will all go in subfolders below Figures/ in your project directory.

ggplot_theme

The name of a ggplot theme or your custom theme. This will be added as a layer to a ggplot object. The default is patchclampplotteR_theme(), but other valid entries include theme_bw(), theme_classic() or the name of a custom ggplot theme stored as an object.

Value

A ggplot object. If save_plot_png == "yes" it will also generate a .png file in the folder Figures/Evoked-currents/CV relative to the project directory. The treatment will be included with the filename.

See also

plot_variance_comparison_data() to make plots of inverse coefficient of variation squared and VMR, which are useful to determine if a mechanism is pre- or post-synaptic.

Examples

  plot_category = 2,
  theme_options = sample_theme_options,
  included_sexes = "both",
  treatment_colour_theme = sample_treatment_names_and_colours,
  save_plot_png = "no"
