Knit2html not replicating functionality of Knit HTML button in R Studio

Question

I'm trying to write a Bash script in Ubuntu 10.04 that opens a Python file which exports a CSV, and then runs the following Rscript with the goal of exporting a HTML with plots from Dashboard.Rmd:

require(knitr)
setwd('/home/sensors/Desktop/')
knit2html('Dashboard.Rmd')
browseURL('Dashboard.html')

Dashboard.Rmd is an R markdown that calls read.csv on the csv from the first step, makes a data frame and creates plots, but that part's working fine. According to this, I figure that Rscript should replicate the action of pressing "Knit HTML" in R Studio. However, the html it creates is identical to the last time Knit HTML was pressed; ie even if the CSV is different, the html doesn't reflect the change.

I also tried using a separate line for knit and markdownToHTML with the same effect. It seems like it doesn't source the code from the Rmd when performing knit. It does update the html properly when I enter the commands from that Rscript into the console of R Studio with Dashboard.Rmd open. However I'm not sure how to translate that into a Bash script. I also tried knit2html with envir=new.env(), envir=R_GlobalEnv, and envir=parent.frame() with no luck. Any help would be appreciated!

因此，事实证明这是cache=TRUE的产物-HTML文件未更改，因为已缓存了所有内容。
