I want to save all my plots from my R environment with ggsave(). How can I save list of plots from environment in R and then use the list as input to ggsave() ? I got some plots with cars from here to illustrate: PlotA <- ggplot(mtcars, aes(x=hp, y=mpg, color=cyl, shape=cyl)) + geom_point(size=3) PlotB <-… Read More Save a list of plots from environment in R
I’m working with the dataset PatentsRD from the Ecdat library and came across a weird behavior with ggplot I have no explanaiton for. I plot two functions poisson distributions (once using the formula and once using dpois) to see wheter they are in fact identical: library(tidyverse) library(Ecdat) data(PatentsRD) plot <- ggplot(data = data.frame(x = c(0:100)),… Read More Weird behavior in ggplot's stat_function()
data(iris) barplot(iris$Sepal.Length, col = iris$Species) The default colors are black, red, and green. How can I change these colors to, say, yellow, blue, orange? For the 3 iris species, respectively? >Solution : Create a named vector of colors and match the species with the vector’s names. Use this to index the colors vector. data(iris) colrs… Read More How to customize bar plot color using base barplot in R
I have an x-axis in logscale, and I would like to display the labels without scientific notation (i.e. not 1e3, but 1,000 instead). I have always done this with label = scales::comma, but now my dataset also has very small values (0.001, for instance). Hence, when I add + scale_x_log10(label = comma), I get an… Read More Axis with label = comma without showing decimals for large numbers
I always wondered how such pictures are made: I am working with the R programming language. I would like to plot a parabola with "random noise" added to the parabola. I tried something like this: x = 1:100 y = x^2 z = y + rnorm(1, 100,100) plot(x,z) But this is still producing a parabola… Read More Plotting a Function With Noise
I’m trying to change the format of y axis in R base plot i.e. plot(x, y, type=’l’). I have y values as numeric and I want values on axis to appear as %. How can I do that? >Solution : x <- 1:3 y <- 1:3 / 4 plot(x, y, type = "l") plot(x, y,… Read More How to change axis values' format to percent in R base plot
I have tried to make a function to quickly make an error bar based on a grouping factor and a numerical value as defined below: #### Function #### quick.error <- function(data,x,y){ d <- data plot.d <- d %>% mutate(x = as.factor(x)) %>% group_by(x) %>% summarise( sd = sd(y, na.rm = TRUE), mean = mean(y, na.rm=TRUE)… Read More Why isn't my custom errorbar function working in R?
I am following this tutorial here https://rpubs.com/brandonkopp/creating-a-treemap-in-r on data visualization. Since the dataset used for this tutorial is no longer available, I learned how to obtain this dataset in the last question I asked (Finding a Dataset That Is No Longer Available?): outlays <- read.csv(‘https://web.archive.org/web/20160705194932if_/https://www.whitehouse.gov/sites/default/files/omb/budget/fy2017/assets/outlays.csv’) str(data) From here, I am now trying to follow the… Read More R Error: <index> contains invalid column names
Am trying to plot 2 different columns of a time series data type in a single plot, however the year appears which seems to block the view of the chart. How do i remove the year in the chart so that i can see the charts nicely? Am trying to plot 2 different columns of… Read More How to remove text that appeared in the chart?
I am trying to make a visualization with logarithmic ticks on all sides of the box. import numpy as np import matplotlib.pyplot as plt x = np.logspace(2, 5, 5) y = 0.5*x**(-1/2) y2 = 0.01*x**(-1/2) y3 = 0.05*x**(-1/3) fig, ax = plt.subplots() ax.plot(x, y, ‘o-‘, label="One") ax.plot(x, y2, ‘*-‘, label="Two") ax.plot(x, y3, ‘–‘, label="Three") ax.set(… Read More Logarithmic Ticks on Top and Right Spine
