[R] Displaying p-values in latex

[Juned Siddique]

Hi. I want to create a table in latex with regression coefficients and their
corresponding p-values. My code is below. How do I format the p-values so
that values less than 0.0001 are formated as <.0001 rather than just rounded
to 0.0000? Thank you.

model<-lm(y~x1+x2)

output<-summary(model)
output<-as.matrix(coefficients(output))
output<-format.df(ouput,cdec=c(2,2,2,4))

latex(output,longtable=TRUE, file="C:/model.tex")
