The data below contains 2 columns I want to plot against each other: . Currently, I can create barplot. But the x-axis is sorted alphabetically. How do I want arrange the x-labels in the order of week: Monday-Sunday?

# Summarize data by date
data$dow = format(data$date, format = "%a")

steps_by_dow <- data %>% 
                group_by(dow) %>% 
                summarize(sum_steps = mean(steps))

# plot histogram for total steps per day
barplot(sum_steps ~ dow, steps_by_dow, xlab = "Daily steps", ylab = "Count (step)", 
     main = "Histogram of the total steps taken per day")

`steps_by_dow$dow <- factor(steps_by_dow$dow, levels = c("Mon", "Tue", "Wed", "Thur", "Fri", "Sat", "Sun"))` and then plot the `barplot`. – Ronak Shah Sep 15 '20 at 05:40
This works. Thanks! That's a really simple trick. – techtana Sep 15 '20 at 05:42
