[R] Function inside Sweave

[Duncan Mackay]

Hi Silvano

I cannot use the data and function as the data is not available to me

for the xtable part using data from xtable try as an example to see if it
fits your needs

data(tli)
head(tli)

for(j in 1:5){ xx <- xtable(tli[1:6,]);  caption(xx) <- paste("Table", j);
print(xx); if(j < 5) cat("\n\n")}

You can amend the xtable part to suit -- the cat command gives some spacing

Regards

Duncan

Subject: [R] Function inside Sweave

Hi,

I have a data set involving 25 Questions (Q1, Q2, ... , Q25), 100 Disciplina
and 5 series. The variables are:

ALUNO DISCIPLINA SERIE TURMA Q1 Q2 Q3 Q4 Q5 Q6 Q7 Q8 ... Q25


I want to create tables associating each of the 25 questions to the
Disciplina.
Something like:

tab1 = table(DISCIPLINA, Q1)
tab1.prop = round(100*prop.table(tab1, 1),  2) tab1.txt = xtable(tab1.prop,
align="l|rrrrr", label='Q1', caption=c("Apresentação da proposta de programa
a ser desenvolvida na disciplina", "Q1")) print(tab1.txt,
format.args=list(big.mark = ".", decimal.mark = ","),
caption.placement='top', table.placement='H')



With the help of a friend, was created the following function:

require(xtable)

DISCIPLINA <- rep(c("A", "B", "C", "D", "E"), 5) for (i in 1:25){
  aux <- paste("Q", i, sep="")
  assign(aux, sample(rep(seq(1:5),5)))
}

cria.tabela <- function(Questao){
  Questao1 <- get(Questao)
  tab1 <- table(DISCIPLINA, Questao1)
  tab1.prop = round(100*prop.table(tab1, 1),  2)
  tab1.txt = xtable(tab1.prop, align="l|rrrrr", label=Questao,
  caption=paste(Questao))
  print(tab1.txt, format.args=list(big.mark = ".", decimal.mark = ","),
  caption.placement='top', table.placement='H') }

geral <- function(){
  for (i in 1:25){
    x<-paste("Q", i, sep="")
    cria.tabela(x)
    }
}

geral()


I need to change the variable DISCIPLINA created in the function by the
variable DISCIPLINA in my dataset, but not working.


Reading data was taken with:

require(foreign)
require(xtable)
dados = read.epiinfo('C:/Colegiado de Veterinária/Dados/A2013/A2013.rec')
head(dados)
tail(dados)
str(dados)
attach(dados)

serie_1 = subset(dados, SERIE=='1')
head(serie_1)
tail(serie_1)
attach(serie_1)


How can I do this?

Thanks a lot,
