latex.cph: LaTeX Representation of a Fitted Cox Model

Description

Creates a file containing a LaTeX representation of the fitted model.

Usage

## S3 method for class 'cph':
latex(object, title,
      file=paste(first.word(deparse(substitute(object))),".tex",sep=""),
      append=FALSE, surv=TRUE, maxt=FALSE, which=NULL, varnames, columns=65, 
      inline=FALSE, before=if(inline)"" else "& &", after="", dec=3,
      pretrans=TRUE, caption, digits=.Options$digits, size="", ...) # for cph fit
## S3 method for class 'lrm':
latex(object, title, file, append, which, varnames,
columns, inline, before, after, pretrans, caption,
digits=.Options$digits, size="", \dots) # for lrm fit
## S3 method for class 'ols':
latex(object, title, file, append, which, varnames,
columns, inline, before, after, pretrans, caption,
digits=.Options$digits, size="", \dots) # ols fit
## S3 method for class 'orm':
latex(object, title, file, append, which, varnames,
columns, inline, before, after, pretrans, caption,
digits=.Options$digits, size="", intercepts=nrp < 10, \dots) # for lrm fit
## S3 method for class 'pphsm':
latex(object, title, file, append, which=NULL, varnames,
columns, inline, before, after, pretrans, caption,
digits=.Options$digits, size="", \dots) # pphsm fit
## S3 method for class 'psm':
latex(object, title, file, append, which=NULL, varnames,
columns, inline, before, after, pretrans, caption,
digits=.Options$digits, size="", \dots) # psm fit

Arguments

object

a fit object created by a rms fitting function.

title

ignored

file,append

see latex.default

surv

if surv=TRUE was specified to cph, the underlying survival probabilities from object$surv.summary will be placed in a table unless surv=FALSE.

maxt

if the maximum follow-up time in the data (object$maxtime) exceeds the last entry in object$surv.summary, underlying survival estimates at object$maxtime will be added to the table if maxt=TRUE.

which,varnames,columns,inline,before,dec,pretrans

see latex.default

after

if not an empty string, added to end of markup if inline=TRUE

caption

a character string specifying a title for the equation to be centered and typeset in bold face. Default is no title.

digits

see latexrms

size

a LaTeX size to use, without the slash. Default is the prevailing size

intercepts

for orm fits. Default is to print intercepts if they are fewer than 10 in number. Set to TRUE or FALSE to force.

...

ignored

Value

• the name of the created file, with class c("latex","file"). This object works with latex viewing and printing commands in Hmisc.

Examples

units(ftime) <- "Day"
f <- cph(Surv(ftime, death) ~ rcs(age)+sex, surv=TRUE, time.inc=60)
w <- latex(f)  #Interprets fitted model and makes table of S0(t)
               #for t=0,60,120,180,\dots   Creates file f.tex
w              #displays image, if viewer installed
latex(f,file="")   # send LaTeX code to the screen
