In my data, Week_death represent the week a patient dies. Some weeks none of the patients are dying.
I am trying to do a barplot of mortality of patients. I would like to show the week without death with an empty barplot.
death <- table(as.numeric(data$Week_death))
barplot(death)
The result is the following
I tried also
plot(death)
and it gave me this result:
How do I add empty weeks?
Thanks in advance
Make your weeks variable a factor and set its levels. table() will retain counts of 0.
# Dummy dataset
data <- data.frame(
week = sample(32:50, 20, replace=TRUE))
# Make week a factor and set levels
data$week <- factor(data$week, levels=c(32:50))
# Get frequencies
# Note that empty factor levels are retained
death <- table(data)
death
#> data
#> 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50
#> 2 2 1 2 1 0 2 0 1 0 1 1 1 2 0 2 1 0 1
barplot(death)
