Advertisements I know there are several answers to this question, but it’s slightly confusing to understand. I believe there are simpler codes than those explained in the current posts. location=c("L1","L2","L1","L2") y=c(5,10,12,12) cat=c("A","A","B","B") se=c(1,2,2,3) df=data.frame(location,y,cat,se) ggplot(data=df, aes(x=location , y=y, fill=cat))+ geom_bar(stat="identity", position = position_stack(reverse=T), width=0.7, size=1) + geom_errorbar(aes(ymin=y-se, ymax=y+se), position = "identity", width=0.5) When I run… Read More In R, how to place error bars at each bar which is stacked?

Advertisements Trying to add the error bars on the bar graph. library(plotly) library(plyr) year <- c("1993","1994","1995","1996") incident <- c(123.2,489.2,281.3,892.1) lower_int <- c(32.1,23.1,11.1,34.2) upper_int <- c(45.3,43.5,25.6,59.0) data <- data.frame(year, incident, lower_int, upper_int) fig <- plot_ly(data, x = ~year, y = ~incident, type = ‘bar’, error_y = ~list(y_min = ~lower_int, y_max = ~upper_int)) fig This code just… Read More Plotting confidence interval from the data in Ploty R

Advertisements I wanted to make a point plot in ggplot and I used geom_point function to do it. To colorize the points, I used levels to fill them either in red or blue. However, now I’m adding the error bars to my point plot with geom_errorbar function, it seems I can’t give the colors I… Read More How can I control the error bar colors to be the same as geom_point colors?

Advertisements It seems like some of my error bars were right below the bars themselves, instead of ± from the mean. Would appreciate it if there’s any advice on this. My plot Image1 My script psbs <- read_csv("psbs.csv") spsbs<-summarySE(data=psbs, measurevar="fv", groupvars=c("Line", "genotype")) P1<- ggplot(data=psbs, mapping = aes(x = factor(genotype), y = fv, fill= Line))+ geom_bar(stat… Read More Faulty positions of error bars in bar chart
