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 the psych package in R",
   caption="df2latex",label="default", char=FALSE, 
    stars=FALSE,silent=FALSE,file=NULL,append=FALSE,cut=0,big=0)
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",silent=FALSE,file=NULL,append=FALSE,cut=0,big=0)
fa2latex(f,digits=2,rowlabels=TRUE,apa=TRUE,short.names=FALSE,cumvar=FALSE,
       cut=0,big=.3,alpha=.05,font.size ="scriptsize",
       heading="A factor analysis table from the psych package in R",
       caption="fa2latex",label="default",silent=FALSE,file=NULL,append=FALSE) 
omega2latex(f,digits=2,rowlabels=TRUE,apa=TRUE,short.names=FALSE,cumvar=FALSE,cut=.2,
        font.size ="scriptsize", 
        heading="An omega analysis table from the psych package in R",
        caption="omega2latex",label="default",silent=FALSE,file=NULL,append=FALSE)
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",silent=FALSE,file=NULL,append=FALSE)
ICC2latex(icc,digits=2,rowlabels=TRUE,apa=TRUE,ci=TRUE,
   font.size ="scriptsize",big.mark=NULL, drop.na=TRUE,
    heading="A table from the psych package in R",
   caption="ICC2latex",label="default",char=FALSE,silent=FALSE,file=NULL,append=FALSE)

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 with abbreviated rownames 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

cut

In omega2latex, df2latex and fa2latex, do not print abs(values) < cut

big

In fa2latex and df2latex boldface those abs(values) > big

alpha

If fa has returned confidence intervals, then what values of loadings should be boldfaced?

icc

Either the output of an ICC, or the data to be analyzed.

ci

Should confidence intervals of the ICC be displayed

silent

If TRUE, do not print any output, just return silently -- useful if using Sweave

file

If specified, write the output to this file

append

If file is specified, then should we append (append=TRUE) or just write to the file

Value

A LaTeX table. Note that if showing "stars" for correlations, then one needs to use the siunitx package in LaTex. The entire LaTeX output is also returned invisibly. If using Sweave to create tables, then the silent option should be set to TRUE and the returned object saved as a file. See the last example.

Examples

# NOT RUN {
df2latex(Thurstone,rowlabels=FALSE,apa=FALSE,short.names=FALSE,
        caption="Thurstone Correlation matrix")
df2latex(Thurstone,heading="Thurstone Correlation matrix in APA style")

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")

#If using Sweave to create a LateX table as a separate file then set silent=TRUE
#e.g., 
#LaTex preamble 
#....
#<<print=FALSE,echo=FALSE>>= 
#f3 <- fa(Thurstone,3)
#fa2latex(f3,silent=TRUE,file='testoutput.tex')
#@
#
#\input{testoutput.tex}

 
# }
