User-facing constructor that provides comprehensive input validation and creates properly validated Cell objects.
Usage
Cell(
type,
content = NULL,
data_subset = NULL,
computation = NULL,
dependencies = NULL,
format = list(),
cached_result = NULL,
footnote_number = NULL,
footnote_text = NULL
)Arguments
- type
Character string specifying cell type. Must be one of: "content", "computation", "separator"
- content
Static text content (required for "static" type)
- data_subset
R expression for data subsetting (required for "computation")
- computation
R expression for calculation (required for "computation")
- dependencies
Character vector of variable dependencies
- format
Named list of formatting options
- cached_result
Cached computation result (for performance)
- footnote_number
Integer footnote number (for footnote cells)
- footnote_text
Character footnote text (for footnote cells)
Examples
# Static cell
Cell(type = "content", content = "Age (years)")
#> Cell [content]
#> Content: 'Age (years)'
# Computation cell
Cell(
type = "computation",
data_subset = expression(data$age[data$group == "Treatment"]),
computation = expression(paste0(round(mean(x), 1), " +/- ", round(sd(x), 1))),
dependencies = c("data", "age", "group")
)
#> Cell [computation]
#> Data subset: expression(data$age[data$group == "Treatment"])
#> Computation: expression(paste0(round(mean(x), 1), " +/- ", round(sd(x), 1)))
# Separator cell
Cell(type = "separator", content = "")
#> Cell [separator]
#> Content: ''
