Hi Greg,
Please find the objective of the code(bold) and code mentioned below. I was
trying to do to achieve the below objective but somehow it's not working.
1.Order assessment based on the latest due date so select input
automatically shows the order of assessment name.
2.Filter based on the one name or multiple names in the select input
library(tidyverse)
#library(stringr) # attached with tidyverse
#library(readr)
library(shiny)
library(dplyr)
ttclasses <- read_csv("~/tmp/ttclasses.csv")
#Filter data
ttclasses <-ttclasses %>%
filter(str_detect(assessment, "Assignment"))
ttclasses <-ttclasses %>% filter(str_detect(name, "Name"))
##Remove NA values.
ttclasses <-ttclasses %>% drop_na("score")
*## Sort assessment based on max due_date*
ttclasses <- ttclasses [order( - due_date, assessment ),]
#Convert to factor
ttclasses$assessment <- factor(ttclasses$assessment)
# please see the formats in help("strptime")
ttclasses$due_date <- as.Date(ttclasses$due_date, format = "%m/%d/%y")
ttclasses$name <- factor(ttclasses$name)
Thanks & Regards
