Create a Summary Table
Here is an example of a regulatory-style table of summary statistics.
This example also introduces the define() function on
create_table(). The define() function allows
you to control many aspects of a column, including the label, format,
width, alignment, and much more:
library(reporter)
# Create temporary path
tmp <- file.path(tempdir(), "example2.rtf")
# Read in prepared data
df <- read.table(header = TRUE, text = '
var label A B
"ampg" "N" "19" "13"
"ampg" "Mean" "18.8 (6.5)" "22.0 (4.9)"
"ampg" "Median" "16.4" "21.4"
"ampg" "Q1 - Q3" "15.1 - 21.2" "19.2 - 22.8"
"ampg" "Range" "10.4 - 33.9" "14.7 - 32.4"
"cyl" "8 Cylinder" "10 ( 52.6%)" "4 ( 30.8%)"
"cyl" "6 Cylinder" "4 ( 21.1%)" "3 ( 23.1%)"
"cyl" "4 Cylinder" "5 ( 26.3%)" "6 ( 46.2%)"')
# Create table
tbl <- create_table(df, first_row_blank = TRUE) %>%
define(var, label = "Variable", blank_after = TRUE, dedupe = TRUE,
format = c(ampg = "Miles Per Gallon", cyl = "Cylinders")) %>%
define(label, label = "") %>%
define(A, label = "Group A", align = "center", n = 19) %>%
define(B, label = "Group B", align = "center", n = 13)
# Create report and add content
rpt <- create_report(tmp, output_type = "RTF",
font = "Times", font_size = 12) %>%
page_header(left = "Client: Motor Trend", right = "Study: Cars") %>%
titles("Table 1.0", "MTCARS Summary Table") %>%
add_content(tbl) %>%
footnotes("* Motor Trend, 1974") %>%
page_footer(left = Sys.time(),
center = "Confidential",
right = "Page [pg] of [tpg]")
# Write out report
write_report(rpt)
# file.show(tmp)
