Exporting summary plm results to latex

I am also interested in the standard errors, but beneath not next to 
the point estimates which is standard in the xtable package.
If you by any chance remember the name of the package or how to do 
it that would be much appreciated!

Cheers,
Sebastian

Hi

If you just want the coefficients.

xtable(summary(fe)$coef)
% latex table generated in R 2.15.1 by xtable 1.7-0 package
% Thu Oct 11 09:04:59 2012
\begin{table}[ht]
\begin{center}
\begin{tabular}{rrrrr}
 \hline
& Estimate & Std. Error & t-value & Pr($>$$|$t$|$) \\
 \hline
x & 0.12 & 0.07 & 1.78 & 0.08 \\
  \hline
\end{tabular}
\end{center}
\end{table}

There is another package whose name eludes me which may help for 

tables which have different outputs to the output of lm etc

HI,

May be you can use library(texreg):

library(plm)

#generating some data
x <- rnorm(270)
y <- rnorm(270)
t <- rep(1:3,30)
i <- rep(1:90, each=3)

data <- data.frame(i,t,x,y)

fe <- plm(y~x,data=data,model="within")
summary(fe)
library(texreg)
fe1<-extract.plm(fe) #extract the plm object

library(xtable)

xtable(do.call(rbind,lapply(fe1,function(x) data.frame(x))))

#Another example.  In this case, you can create two tables from 

the zz1 list

data("Produc", package = "plm")
   zz <- plm(log(gsp) ~ log(pcap) + log(pc) + log(emp) + unemp, 

data = Produc, index = c("state","year"))

zz1<-extract.plm(zz)


lapply(lapply(zz1,function(x) data.frame(x)),xtable)

Subject: [R] Exporting summary plm results to latex

Dear all,

I am trying to export my fixed effect results to Latex. I am 

using the plm package with the summary function. However, it does 
not look like apsrtable, stargazer, or any other package can 
accompany using the plm package.

I am interested in a classic table with the coefficient in one 

row followed by the standard error in paranthesis in the next row 
and stars by the coefficient to show relevant coefficient level.

coefficient 1     xxx**
           (xxx)

Here is a reproducible example:

library(plm)

#generating some data
x <- rnorm(270)
y <- rnorm(270)
t <- rep(1:3,30)
i <- rep(1:90, each=3)

data <- data.frame(i,t,x,y)

fe <- plm(y~x,data=data,model="within")
summary(fe)

If there is an alternative to using the plm package that works 

with any of the export to latex packages, I would be very 
interested to know. Otherwise, any ideas of how to solve this 
problem are very welcome. I almost exclusively use fixed effect 
panel models, and the problem of exporting results to Latex is one 
of the things preventing me from switching entirely from Stata to R.

Kind regards,
Sebastian
