tableNominal {reporttools} | R Documentation |
Many data analyses start with a display of descriptive statistics of important variables. This function takes a data frame of nominal variables and possible grouping (such as e.g. treatment), weighting, and subset variables and provides a LaTeX table of descriptive statistics separately per group and jointly for all observations, per variable.
tableNominal(vars, weights = NA, subset = NA, group = NA, miss.cat = NA, print.pval = c("none", "fisher", "chi2")[1], vertical = TRUE, cap = "", lab = "", font.size = "footnotesize", longtable = TRUE, nams = NA)
vars |
A data frame of nominal variables. See nams for an alternative
way of specifying the variables to be displayed. |
weights |
Optional vector of weights of each observation. |
subset |
Optional logical vector, indicates subset of observations to be used. |
group |
Optional grouping variable. |
miss.cat |
Vector specifying the factors in vars that should have their NA s transformed to a separate category. |
print.pval |
Add p-values of Fisher's exact or chi^2 test for a difference of distributions between groups to the table, if there is more than one group. |
vertical |
If TRUE , add vertical lines to the table, separating labels and groups, if applicable. |
cap |
The caption of the resulting LaTeX table. |
lab |
The label of the resulting LaTeX table. |
font.size |
Font size for the generated table in LaTeX. |
longtable |
If TRUE , function makes use of package longtable in LaTex to generate tables that
span more than one page. If FALSE , generates a table in tabular environment. |
nams |
A vector of strings, containing the names corresponding to the variables in vars , if vars
is not a data frame but a list of variables. These are then the names that appear in the LaTeX table.
This option is only kept for backward compatibility. |
Outputs the LaTeX table.
If either one of the arguments group
, weights
, or subset
is different from NA
and if vars
is a list, then it is assumed that all variables
in vars
are of equal length.
If longtable = TRUE
(which is the default), the function generates a table that may be more than one page
long, you need to include the package longtable in the LaTeX source.
If a list of variables is given to vars
, not all of these variables need to be of the same length. However,
note the Warning below.
