Title: Create Elegant Table 1 in HTML/'LaTeX' for Bio-Statistics
Version: 2.2.0
Description: Creates the "table one" of bio-medical papers. Fill it with your data and the name of the variable which you'll make the group(s) out of and it will make univariate and bivariate analysis, and parse the result into an HTML or 'LaTeX' table ready to paste into a paper.

Create a table of descriptive analysis of a dataset

Description

Displays together the univariate analysis (mean/median; SD/IQR; proportions) and the bivariate analysis (t test/Wilcoxon, ANOVA/Kruskal-Wallis, Chi2 or Fisher) of every variable of a dataset. The univariate analysis can be sub-grouped by a variable of interest of n levels; the test applied to each variable follows from its type and from normality.

Usage

descTab(
  data,
  group = "",
  quanti = TRUE,
  quali = TRUE,
  na.print = FALSE,
  pvalue = TRUE,
  digits.p = 3L,
  digits.qt = 1L,
  digits.ql = 1L,
  normality = "normal",
  parallel = FALSE,
  mc.cores = 0
)

Arguments

data

A dataset. Needs to be a data.frame or a tibble.

group

Optional. The name of the factor variable to make sub-groups comparisons with; it must have at least two non empty levels. Omitted, "" or NULL, the table has a single Total column. Rows with a missing value for it are dropped, and its unused levels are dropped, both with a warning.

quanti, quali, na.print, pvalue

Logical. If false, won't display quantitative/qualitative/Missing values/pvalues variable results. quanti and quali cannot both be FALSE.

digits.p

Integer. Significant digits for p value

digits.qt

Integer. Significant digits for mean/median, SD/IQR

digits.ql

Integer. Significant digits for proportions

normality

One of "normal", "non normal" or "assess". "normal" applies the parametric tests (mean (SD), t test/ANOVA) to every quantitative variable, "non normal" the non parametric ones (median (IQR), Wilcoxon/Kruskal-Wallis), and "assess" decides variable by variable with a Shapiro-Wilk test at the 5% level.

parallel

Logical. Make analysis using parallel from parallel::mclapply().

mc.cores

If parallel is TRUE, how many cores to use. The default, 0, uses all the cores but one.

Details

Only numeric, integer and factor (including ordered factor) variables are described. A variable of any other type is ignored with a warning, as is a variable whose test cannot be computed: its p value is then NA and the rest of the table is still produced.

Value

An S4 object of class parseClass. Its ⁠["table"]⁠ element is a data.frame (whether or not there is a group, and also when data is a tibble) with a var column, one column per level of group, a Total column and, if there is a group and pvalue = TRUE, a pvalue column.

                    ordered = TRUE)
)
patients$crp[sample(n, 15)] <- NA

# Compare the two arms. With normality = "assess", age (normal) is described
# by mean (SD) with a t test, crp (skewed) by median (IQR) with a Wilcoxon test
tab <- descTab(patients, group = "arm", normality = "assess", na.print = TRUE)
tab["table"]

# No group: a single Total column, no test
descTab(patients)["table"]

# Quantitative variables only, two decimals
descTab(patients, group = "arm", quali = FALSE, digits.qt = 2)["table"]

# Render it (see parseClassFun() for the layout options)
