What is gridExtra?

What is gridExtra?

gridExtra-package. Miscellaneous Functions for “Grid” Graphics. Description. Provides a number of user-level functions to work with “grid” graphics, notably to arrange multiple grid-based plots on a page, and draw tables.

What is the gridExtra package in R?

The gridExtra package provides useful extensions to the grid system, with an emphasis on higher-level functions to work with grid graphic objects, rather than the lower-level utilities in the grid package that are used to create and edit specific lower-level elements of a plot.

What is a Cowplot?

The cowplot package is a simple add-on to ggplot. It provides various features that help with creating publication-quality figures, such as a set of themes, functions to align plots and arrange them into complex compound figures, and functions that make it easy to annotate plots and or mix plots with images.

What is a Gtable?

A GTABLE file is a shortcut that was previously used to open a fusion table created in Google Fusion Tables and stored in Google Drive. GTABLE files are now obsolete, as Google has discontinued Google Fusion Tables.

What does grid mean in R?

Grid is an add-on package for the R language and environment for statistical computing and graphics. It provides a set of graphical functions which support a great deal of flexibility in the layout of graphics.

Is a Ggplot a Grob?

The graphics library underneath all of ggplot2’s graphical elements are really composed of grob’s because ggplot2 uses grid underneath.

What is in the Tidyverse package?

As of tidyverse 1.3.0, the following packages are included in the core tidyverse:

• ggplot2. ggplot2 is a system for declaratively creating graphics, based on The Grammar of Graphics.
• dplyr.
• tidyr.
• readr.
• purrr.
• tibble.
• stringr.
• forcats.

What is a plot grid?

Plot Grids consist of columns (Plot Lines) and cards (Plot Points). The left-most column is a good place for Scenes or Chapters of your book. Plot Lines are Plots and Sub-Plots. Pro Tip: Think of each vertical column as a Sub-Plot, and the left-most column as a list of Scenes.

How do I remove a legend in R?

Remove a ggplot legend

1. Remove the legend title: p + theme(legend. title = element_blank()) .
2. Hide the entire legend to create a ggplot with no legend. Example of R code: p + theme(legend. position = “none”) .
3. Hide legend for a specific geometry, say geom_text() . Just specify the argument show.

What is ggplotGrob?

ggplotGrob is the same as ggplot_gtable(ggplot_build(x)) ; it’s just a convenience function to save some typing. The end goal is to convert the ggplot object, which is essentially a list describing how to build the plot, into a gtable, which is a grid graphical object (grob) that can be drawn on a device.

What is grid in radiography?

Grids are placed between the patient and the x-ray film to reduce the scattered radiation reaching the detector (produced mainly by the Compton effect) and thus improve image contrast.

What can I do with the gridextra package?

The gridExtra package provides a few conventient constructor functions, e.g. Let’s have a closer look at the gtable we created earlier.

How to make a multi panel graph with gridextra?

Through its function grid.arrange, you can make a multi-paneled graph using ggplot2 plots, lattice plots, and more (although, not regular R plots…I think). So, let’s see the same example, but with gridExtra.

Why do we use individual textgrobs in grid graphics?

We use individual textGrob and rectGrob elements for each cell, instead of relying on the vectorised implementation of these functions. The reason is practical: it is much easier to place, measure, and customise individual grobs, than modify the graphical parameters and positions of a single vectorised grob.

When to use plotmath notation in grid graphics?

Plotmath notation may be used, with the parse=TRUE argument. Note that this is applied to individual strings of text, and reverts to standard text if parsing fails (this is useful when mixing multiline text with plotmath in different cells). The formatting is controlled by themes, which are nested lists of graphical parameters.
