convert factor to time format in r

In base R, you can use as.POSIXct or strptime along with format to convert the factor variable to datetime class (POSIXlt/POSIXct).

transform(df, session_start_text = as.POSIXct(session_start_text, format = "%T"), 
              session_end_text = as.POSIXct(session_end_text, format = "%T"))

In lubridate, we can use hms to convert the columns to "Period" class

library(dplyr)
library(lubridate)
df %>%
  mutate(session_start_text = hms(session_start_text), 
         session_end_text = hms(session_end_text))

Moreover, there is also anytime::anytime() function which helps in converting to date time values.
