Reporting Workflows

Parameterized Caption

Reused Text

Parameterized reporting keeps the same template while changing the values inserted into it.

Program

Play the script to choose a region and see the caption update from the same template.

parameterized_caption.R 
regions <- c("north", "south", "west")
region_index <- 
count <- c(12, 9, 15)[region_index]
region <- regions[region_index]
caption <- paste("Region", region, "has", count, "records")
cat(caption, "\n", sep = "")

regions <- c("north", "south", "west")
region_index <- 
count <- c(12, 9, 15)[region_index]
region <- regions[region_index]
caption <- paste("Region", region, "has", count, "records")
cat(caption, "\n", sep = "")

regions <- c("north", "south", "west")
region_index <- 
count <- c(12, 9, 15)[region_index]
region <- regions[region_index]
caption <- paste("Region", region, "has", count, "records")
cat(caption, "\n", sep = "")
parameter `region_index` is a small parameter that controls the report value.
lookup `regions[region_index]` maps the parameter to display text.
template `paste` fills the same caption shape with selected values.
