Advertisements I would appreciate some help with changing the axis titles given the format of my current ggplot. I’ve tried the usual arguments such as scale_x_discrete() and adding the associated labels, yet with no success. However, overall, my goal is to keep the current format of the stacked bar, yet change 1,2,3 on the x-axis… Read More Customising X-axis on Stacked Bar Graph GGplot2
Advertisements I am working with the R programming language. I have the following dataset: library(stringi) library(dplyr) library(tidyverse) set.seed(123) n <- 100 final <- data.frame(id = 1:n, var1 = rnorm(n), var2 = rnorm(n), var3 = rnorm(n)) final$new_id <- stri_rand_strings(n, 6, pattern = "[A-Za-z0-9]") The dataset looks something like this: id var1 var2 var3 new_id 1 1… Read More R: Replacing Axis Labels With Another Variable
Advertisements I have a data that look like this: cis_distance_freq4 # A tibble: 6 × 2 distance freq <dbl> <dbl> 1 0 NA 2 1000 4380 3 10000 4381 4 40000 4535 5 80000 4536 6 1000000 4558 hist(cis_distance$freq) I want to plot in such a way that x axis is distance and y axis… Read More error while plotting hist plot for a dataframe in R
Advertisements 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
Advertisements 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 =… Read More Weird behavior in ggplot's stat_function()
Advertisements 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)… Read More How to customize bar plot color using base barplot in R
Advertisements 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… Read More Axis with label = comma without showing decimals for large numbers
Advertisements 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… Read More Plotting a Function With Noise
Advertisements 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,… Read More How to change axis values' format to percent in R base plot
Advertisements 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,… Read More Why isn't my custom errorbar function working in R?
