Questions tagged [ggpmisc]

The ggpmisc tag should be used for questions related to the use of R package 'ggpmisc'.

The ggpmisc tag should be used for questions related to the use of R package 'ggpmisc'. Bug reports and requests for enhancements should not be posted here, but instead informed to the maintainer by raising an issue at https://bitbucket.org/aphalo/ggpmisc/issues.

The 'ggpmisc' R package is available through CRAN, and includes detailed documentation. This same documentation is also available in HTML format at http://docs.r4photobiology.info/ggpmisc and can be looked at without need to install the package. The source code of the package is in a public Git repository at https://bitbucket.org/aphalo/ggpmisc.

Functions are provided to convert time series objects into data frames or tibbles suitable for plotting with R package 'ggplot2'. To complement these functions ggplot() methods for "ts" and "xts" classes are also defined.

Different statistics, geometries and functions add facilities for labelling peaks and valleys, generating labels for fitted models including polynomial equations, highlighting deviations from a model fit, and for filtering-out regions of plot panels with high densities of observations (with stats designed to work nicely together with R package 'ggrepel').

Geometries for adding layers with inset tables, ggplots or 'grid' grobs are also defined together with versions of geom_text and geom_label that use 'grid' npc coordinates instead of data coordinates supported by new aesthetics npcxand npcy and corresponding scales.

Editing *row* names of tabular display when using stat_fit_tb() in ggpmisc & ggplot

While stat_poly_eq() allows variable names to be changed using eq.with.lhs and eq.x.rhs, a similar functionality does not seem to be available within stat_fit_tb(), according to my reading of the ggpmisc documentation. Is there a way of modifying…

Change table theme when using ggpmisc::geom_table_npc

This question uses 'ggpmisc' version 0.3.4 or earlier, see answer below for version 0.3.5 or later. I like the newish geom_table_npc in ggpmisc which provides a simple way to add a table to a ggplot and works particularly well with transformed…

Modifying the decimal mark of stat_poly_eq

I use the stat_poly_eq function from the ggpmisc package to add the regression equation in my ggplots. It works perfectly. However, I'd like to change the decimal mark of the equation from period to comma, and I can't figure out how to do this. Any…

How to fill the background of a stat_poly_eq equation (ggpmisc) using ggplot2?

Is there a way to fill the background of a stat_poly_eq equation ggpmisc with white color (or any other color) so that the black lines of the panel.grid are hidden? # Data df <- data.frame(x = c(1:100)) df$y <- 2 + 3 * df$x + rnorm(100, sd =…

R scientific notation in stat_poly_eq

I am currently using the code for stat_poly_eq in ggplot2 and was wondering if there is a way to always get the values on the graph in xe+1? So far it only gives me the Xx10^1 when the value is very high or very low. I would like it to always be in…

Color ggscatter by R and P values

I'm plotting a wrapped ggscatter like the image below. What I want is to color differently according to the R and P values. For example, when P is not significant, I want the plot gray; when P is significant is want the plot colored according the R…

How to force trailing zeroes in 'polynom::polynomial' object? (specifically to modify behavior of stat_lm and stat_regline_equation from ggpubr)

I am trying to modify how stat_regline_equation displays the regression line equation on a plot made with ggscatter from the R package ggpubr. Specifically, I want to show a consistent number of digits of coefficients, even when some rounded…

Is there a neat approach to label a ggplot plot with the equation and other statistics from geom_quantile()?

I'd like to include the relevant statistics from a geom_quantile() fitted line in a similar way to how I would for a geom_smooth(method="lm") fitted linear regression (where I've previously used ggpmisc which is awesome). For example, this code: #…

Label ggplot with group names and their equation, possibly with ggpmisc?

I would like to label my plot, possibly using the equation method from ggpmisc to give an informative label that links to the colour and equation (then I can remove the legend altogether). For example, in the plot below, I would ideally have the…

What is the best way to calculate and display peaks of a ggplot2::geom_density() object?

I'm trying to find an easy and intuitive way to calculate and display the peaks of a ggplot2::geom_density() object. This blog explains how to do it in base R, but it is a multistep process. But it seems much more intuitive to use the stat_peaks()…
