generate plots in loop to get markdown/html - possible bug

[Szilard]

I'm trying to generate text-plot pairs with markdown and ultimately
html output:

```{r echo=FALSE}
library(ggplot2)
for(i in 1:3) {
cat(i)
plt <- qplot(x,y, data=data.frame(x=1:10,y=rnorm(10)) )
print(plt)
}
```

I'd like to get this:

1
plot1
2
plot2
...

Instead, I get this:

1
2
plot1
3
plot2
plot3

Is this a bug? Any work around? (I have lots of plots and the labels
would make it easy to "navigate" the html)

I do not understand this either. Putting cat() after qplot() seems to work.

You may report this to Hadley, though
(https://github.com/hadley/evaluate/issues).

library(evaluate)
evaluate('library(ggplot2)

for(i in 1:3) {
cat(i)
plt <- qplot(x,y, data=data.frame(x=1:10,y=rnorm(10)) )
print(plt)

}')
