Legoplots in R (3D barplots in R)

I previously mentioned these, but I thought about it some more and went ahead and wrote an R implementation.  With very little work you could rejig this code to display all kinds of 3D bar plots; I’ve commented the code thoroughly so it should be easy to follow.  Immediately below is an example plot and…

Building Barplots with Error Bars

Bar charts are a pretty common way to represent data visually, but constructing them isn’t always the most intuitive thing in the world. One way that we can construct these graphs is using R’s default packages. Barplots using base R Let’s start by viewing our dataframe: here we will be finding the mean miles per

Using R: barplot with ggplot2

Ah, the barplot. Loved by some, hated by some, the first graph you’re likely to make in your favourite office spreadsheet software, but a rather tricky one to pull off in R. Or, that depends. If you just need a barplot that displays the value of each data point as a bar — which is

R: Barplot with absolute and relative values

In this short tutorial I will show how you can add the relative amount over the barplots, such that you have both, the absolute and relative Information in the plot. First, I create some artificial SNPs and TPMT-genotype.

Adding lines or points to an existing barplot

Sometimes you will need  to add some points to an existing barplot. You might try but you will get a funky looking line/points. It’s a bit squeezed. This happens because bars are not drawn at intervals 1:10, but rather on something else. This “else” can be seen if you save your barplot object. You will

MultBar : Advanced multiple barplot with SEM

Producing this kind of graphs (below) in R can be a pain in the a*s. Here is a simple code that requires that data are presented in lists (see the example below). multbar <- function(list.of.lists,...,condnames=0,pal=colorRampPalette(c('grey','cornsilk')),seriesnames=0,legendpos='topleft',legh=TRUE,do.pty='s') { par(pty=do.pty,mgp=c(1.9,0.8,0),oma=c(0,0,0,0),mar=c(4,3,2,1),bg='transparent',bty='o',tck=0.02,yaxs='i') NofList <- length(list.of.lists) NofSubList <- length(list.of.lists]) if(condnames==0){condnames=c(1:NofList)} if(seriesnames==0){seriesnames=c(1:NofSubList)} dim.mat.treat <- (NofList+1)*NofSubList pos <- c(1:dim.mat.treat) pos <- matrix(pos,nrow=(NofList+1)) nbreaks
