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 gallon by number of cylinders and number of gears. View(mtcars) We begin by aggregating our data by cylinders and gears and specify that we want to return the mean, standard deviation, and number of observations for each group: myData <- aggregate(mtcars$mpg, by = list(cyl = mtcars$cyl, gears = mtcars$gear), FUN = function(x) c(mean = mean(x), sd = sd(x), n = length(x))) After this, we'll need to do a little manipulation since the previous function returned matrices instead of vectors myData <- do.call(data.frame, myData) And now let's compute the standard error for each group. We can then rename the columns just for ease of use. myData$se <- myData$x.sd / sqrt(myData$x.n) colnames(myData) <- c("cyl",
a barplot with errorbars Now this is a scatter plot with error bars in r tricky one: I wrote a script to plot a barplot with errorbars. I used the following https://www.r-bloggers.com/building-barplots-with-error-bars/ script: #barplot where x is the independent on the x-axis, y is the #dependent on the y-axis and z is the independent given by #different colored bars anova.plot<-function(x, y, z, ylab="y", xlab="x", ylim=c(0, max(xx)+max(yy)), http://rstatistics.tumblr.com/post/470327991/make-a-barplot-with-errorbars-now-this-is-a length=0.05){ #height of the bars xx<-tapply(y,list(z,x),mean) #standard deviation yy<-tapply(y,list(z,x),sd) #number of replicates zz<-tapply(y,list(z,x),length) #standard error er<-yy/sqrt(zz) #number of colors for bars w<-length(levels(z)) #simple barplot without the errorbars barx<-barplot(xx, col=c(1:w), beside=T, ylab=ylab, xlab=xlab, ylim=ylim,xpd=FALSE) #box around the plot box() #error bars arrows(barx,xx+er, barx, xx, angle=90, code=1, length=length) #legend (after making the plot, indicate where the legend has #to come with the mouse) legend(locator(1),c(levels(z)),fill=c(1:w),bty="n",cex=0.8) } If you have set your palette to: palette(c("grey25","grey50","grey75","white")) you get a plot like the one above if you use: anova.plot(x,y,z) (6 years ago) archive : rss : theme "2001" by 54mf : powered by Tumblr

Here is the kind of figure I have been able to get up to now, and this is ok for what I need: And here is my script: #create dataframe Gene<-c("Gene1","Gene2","Gene1","Gene2") count1<-c(12,14,16,34) count2<-c(4,7,9,23) count3<-c(36,22,54,12) count4<-c(12,24,35,23) Species<-c("A","A","B","B") df<-data.frame(Gene,count1,count2,count3,count4,Species) df mean1<-mean(as.numeric(df[1,][c(2,3,4,5)])) mean2<-mean(as.numeric(df[2,][c(2,3,4,5)])) mean3<-mean(as.numeric(df[3,][c(2,3,4,5)])) mean4<-mean(as.numeric(df[4,][c(2,3,4,5)])) Gene1SpeciesA.stdev<-sd(as.numeric(df[1,][c(2,3,4,5)])) Gene2SpeciesA.stdev<-sd(as.numeric(df[2,][c(2,3,4,5)])) Gene1SpeciesB.stdev<-sd(as.numeric(df[3,][c(2,3,4,5)])) Gene2SpeciesB.stdev<-sd(as.numeric(df[4,][c(2,3,4,5)])) ToPlot<-c(mean1,mean2,mean3,mean4) #plot barplot plot<-matrix(ToPlot,2,2,byrow=TRUE) #with 2 being replaced by the number of genes! tplot<-t(plot) BarPlot <- barplot(tplot, beside=TRUE,ylab="count", names.arg=c("Gene1","Gene2"),col=c("blue","red")) #add legend legend("topright", legend = c("SpeciesA","SpeciesB"), fill = c("blue","red")) #add error bars ee<-matrix(c(Gene1SpeciesA.stdev,Gene2SpeciesA.stdev,Gene1SpeciesB.stdev,Gene2SpeciesB.stdev),2,2,byrow=TRUE)*1.96/sqrt(4) tee<-t(ee) error.bar(BarPlot,tplot,tee) The problem is that I need to do this for 50 genes, and 4 species, so my script is gonna get super super long and I guess this is not optimized... I tried to find help here but I can't figure out a better way to do what I'd like. If I did not need error bars I could adapt this script but
