Barchart for each row in dataframe

Question

I have a dataframe and I want a barplot for each row in this dataframe.

for(i in levels(myDf$name)) {
    barplot(cbind(unlist(myDf[i, 1:2]), unlist(myDf[i, 3:4])), beside=TRUE)
}

However, that does not work. It gives me no output... How would I plot that in one window so that I can export it to a file?!

*edit:

myDf<-data.frame(name=c('xyz','ybc','def'),
              var1=c(2,8,7), 
              var2=c(1,4,5),
              var3=c(3.8,2.5,8.4),
              var4=c(93.8,42.5,91.4))

Can you please give a glimpse of dataset by head() or dput()? — Kunal Puri

@LukeSingham no, nothing. The plot window simply stays empty. — four-eyes

If I understood it correctly, then here is an alternative.

data <- t(myDf[,2:5])

colnames(data) <- myDf$name

barplot(data,legend.text = rownames(data),beside=T,xlab='Row', ylab='Value')

for(i in seq(myDf$name)) {
    barplot(cbind(unlist(myDf[i, 1:2]), unlist(myDf[i, 3:4])), beside=TRUE)
}

same as with my code. The plot window stays empty!+

Interesting, I get errors when using levels, using seq fixes the problem for me.
