In general, use cat (see help("cat")) for printing your output, e.g.
<<echo=FALSE>>=
cat(levels(mydata$Firms)[mydata$Firms], "\n")
cat(mydata$Year, "\n")
# etc.
@
For your specific case you may also be interested in help("xtable",
package="xtable") along with the <<...,results=tex>>= Sweave construct.
For an R version of the output you want, a starting point may be
for (f in levels(mydata$Firms)) {
cat(f, "\n")
print(t(mydata[mydata$Firms == f, 2:5]))
}
which gives
electrolux

Year 1995 1996 1997
IIA 100 340 35
IIB 45 67 99
IIC 65 97 31
fiat

Year 1995 1996 1997
IIA 76 567 453
IIB 34 35 89
IIC 45 66 37
Hope this helps a little.

Dear list,
I have a question about the interaction between R code and Latex language trough the
Sweave function in the package "utils".
What I'm trying to do is to write a report. Contrary to the examples shown in the
Sweave Manual in which table already constructed by R are "exported" on Latex
files, what I would like to do is to build a table in which I combine text and specific
columns of my data frame. I will give you the following example to be much more clear.
Suppose I have a data frame like this:
Firms Year IIA IIB
IIC
electrolux 1995 100 45
65
electrolux 1996 340 67
97
electrolux 1997 35 99
31
fiat 1995 76
34 45
fiat 1996 567
35 66
fiat 1997 453 89
37
Where IIA is the turnover of the firm, IIB is the production and IIC is the
cost of labour.
I would like to get a table like this in the latex format this:
Firms 1
electrolux
-----------------------------------------------------------------------------------
variables 1995 1997 1997
----------------------------------------------------------------------------------
turnover 100 340 35
production 45 67 99
cost of labour 65 97 31
--------------------------------------------------------------------------------
I use the following code:
\documentclass[a4paper]{article}
\title{example}
\begin{document}
\maketitle
<<echo=F>>=
mydata$firms
@
variables
<<echo=F>>=
mydata$year
@
and so on. I have two problem, first I'm not able to put on the same line text
and output of R. So on my Latex document I get for example
variable
1995 1996 1997
and I don't want this. The secondo problem is that at the beginnig of the R
output I get the index, namely
variable
[1] 1995 1996 1997
and I don't want to see it.
Anyone Knows how to do it or if there is another package in R that give me the
possibility to create a Report by constructing table without any problems???
