Data File

Name of the data file = toto.rmd

Contains following:

##1st

```{r clock, cache=TRUE}
x <- 600
x
```


##2nd

```{r, cache=TRUE, cache.path="toto_cache/", dependson="clock"}

x+5
```

Problem

The second chunk is not being updated. Previously x was 500, after updating it to 600, I get following after knit HTML in RSTUDIO:

1st
x <- 600
x
## [1] 600
2nd
x+5
## [1] 505

What am I missing here?
