Keeps the rows you mention in the printed table.
Compared to dplyr::filter(), show_rows does not remove the
rows from the actual data frame, they are removed only for printing.
show_rows(x, ...)condformat_tbl object
Expressions used for filtering
A condformat_show_rows object, usually to be added to a condformat_tbl object as shown in the examples
library(condformat)
data(iris)
x <- head(iris)
cf <- condformat(x) %>% show_rows(Sepal.Length > 4.5, Species == "setosa")
if (FALSE) {
print(cf)
}
# Use it programatically
expr_as_text <- 'Sepal.Length > 4.5'
expr <- rlang::parse_expr(expr_as_text)
cf <- condformat(x) %>% show_rows(!! expr)
if (FALSE) {
print(cf)
}
# With multiple arguments:
expr_as_text <- c('Sepal.Length > 4.5', 'Species == "setosa"')
exprs <- lapply(expr_as_text, rlang::parse_expr)
cf <- condformat(x) %>% show_rows(!!! exprs)
if (FALSE) {
print(cf)
}
