# [R] clock24.plot/radial plot

```Looks like you forgot to load the lubridate package

library(lubridate)

You are calling functions days(), hours(), minutes(), seconds(), and hour() which all come from that package.

Kind Experts,
Many thanks for your guide. I have tried to figure out something that
can help me plot my own data using the examples you referred me to. I
copied part of the code as:

set.seed(44)
N=500
events <- as.POSIXct("2011-01-01", tz="GMT") +
days(floor(365*runif(N))) +
hours(floor(24*rnorm(N))) +  # using rnorm here
minutes(floor(60*runif(N))) +
seconds(floor(60*runif(N)))
hour_of_event <- hour(events)
# make a dataframe
eventdata <- data.frame(datetime = events, eventhour = hour_of_event)
# determine if event is in business hours
eventdata\$Workday <- eventdata\$eventhour %in% seq(9, 17)
library(circular)
eventdata\$eventhour <- circular(hour_of_event%%24, # convert to 24 hrs
units="hours", template="clock24")
rose.diag(eventdata\$eventhour, bin = 24, col = "lightblue", main =
"Events by Hour (sqrt scale)",
prop = 3)
I tried to run the above but got an error message: "Error in
eval(expr, envir, enclos) : could not find function "days"
I was thinking that if I could run this code, I can see what is doing
and then start trying to see if I can adapt it to solve my problem.

Thank you so much for further assistance.
