df2latex: Convert a data frame, correlation matrix, or factor analysis output to a LaTeX table

Description

A set of handy helper functions to convert data frames or matrices to LaTeX tables. Although Sweave is the preferred means of converting R output to LaTeX, it is sometimes useful to go directly from a data.frame or matrix to a LaTeX table. cor2latex will find the correlations and then create a lower (or upper) triangular matrix for latex output. fa2latex will create the latex commands for showing the loadings and factor intercorrelations. As the default option, tables are prepared in an approximation of APA format.

Usage

df2latex(x,digits=2,rowlabels=TRUE,apa=TRUE,short.names=TRUE,font.size ="scriptsize",
big.mark=NULL,drop.na=TRUE, heading="A table from R",caption="df2latex",label="default", 
char=FALSE,stars=FALSE)
cor2latex(x,use = "pairwise", method="pearson", adjust="holm",stars=FALSE,
       digits=2,rowlabels=TRUE,lower=TRUE,apa=TRUE,short.names=TRUE,
     font.size ="scriptsize",
      heading="A correlation table from the psych package in R.",
      caption="cor2latex",label="default")
fa2latex(f,digits=2,rowlabels=TRUE,apa=TRUE,short.names=FALSE,cumvar=FALSE,
       font.size ="scriptsize",
       heading="A factor analysis table from the psych package in R",
       caption="fa2latex",label="default") 
irt2latex(f,digits=2,rowlabels=TRUE,apa=TRUE,short.names=FALSE,
       font.size ="scriptsize",
     heading="An IRT factor analysis table from R",caption="fa2latex",label="default")

Arguments

x
A data frame or matrix to convert to LaTeX. If non-square, then correlations will be found prior to printing in cor2latex
digits
Round the output to digits of accuracy. NULL for formatting character data
rowlabels
If TRUE, use the row names from the matrix or data.frame
short.names
Name the columns 1 .. N to save space
apa
If TRUE formats table in APA style
cumvar
For factor analyses, should we show the cumulative variance accounted for?
font.size
e.g., "scriptsize", "tiny" or anyother acceptable LaTeX font size.
heading
The label appearing at the top of the table
caption
The table caption
lower
in cor2latex, just show the lower triangular matrix
f
The object returned from a factor analysis using fa or irt.fa.
label
The label for the table
big.mark
Comma separate numbers large numbers (big.mark=",")
drop.na
Do not print NA values
method
When finding correlations, which method should be used (pearson)
use
use="pairwise" is the default when finding correlations in cor2latex
adjust
If showing probabilities, which adjustment should be used (holm)
stars
Should probability asterixs be displayed in cor2latex (FALSE)
char
char=TRUE allows printing tables with character information, but does not allow for putting in commas into numbers

Value

  • A LaTeX table. Note that if showing "stars" for correlations, then one needs to use the siunitx package in LaTex.

df2latex(describe(sat.act)[2:10],short.names=FALSE)
cor2latex(Thurstone)
cor2latex(sat.act,short.names=FALSE)
fa2latex(fa(Thurstone,3),heading="Factor analysis from R in quasi APA style")
