You can create a monthly calendar in R with the
calendR package. Specify the month in the
month argument (from 1 to 12).
# install.packages("calendR") library(calendR) # Specify the year and the month calendR(year = 2022, month = 3)
The function allows you to add text to some days. For that purpose you can pass a vector with the text to
text argument and specify its position (the days) with
# install.packages("calendR") library(calendR) # Add text to the days calendR(year = 2021, month = 3, text = c("Event 1", "Event 2"), text.pos = c(4, 8), text.col = "blue")
Moreover, you can colorize some days to indicate some event. In this scenario you will need to create a vector of
NA and fill it with the events in order to pass it to
special.days argument. The colors can be customized with
special.cols and the legend position with
# install.packages("calendR") library(calendR) # Vector of NA which length is # the number of days of the month fills <- rep(NA, 31) # Add the events to the desired days fills[c(4, 10, 15, 22)] <- "Event 1" fills[c(1, 5, 17, 30)] <- "Event 2" # Specify the year calendR(year = 2022, month = 3, special.days = fills, special.col = 3:4, legend.pos = "bottom")
You can also customize more arguments, such as the start of the week, the background color or the line type of the calendar, as shown in the example below. Recall to type
?calendR for a full list or arguments with their corresponding description.
# install.packages("calendR") library(calendR) calendR(month = 7, year = 2022, start = "M", # Start on Monday special.days = "weekend", # Colorize weekends special.col = "lightblue", # Weekends color bg.col = "#f7f7f7", # Background color lty = 2) # Line type
