 ### Installation
 The xROI R package has been published on The Comprehensive R Archive Network (CRAN). The latest tested xROI package can be installed from the [CRAN packages repository](https://cran.r-project.org/web/packages/xROI) by running the following command in an R environment:
-```{r, echo=TRUE}
+```{r, echo=TRUE, eval=FALSE} 
 
 utils::install.packages('xROI', repos = "http://cran.us.r-project.org")
 
 ```
 
 Alternatively, the latest beta release of xROI can be directly downloaded and installed from the GitHub repository:

 ### Launch
 
 A comprehensive user manual for low-level image processing using xROI is available from [xROI.pdf](https://cran.r-project.org/web/packages/xROI/xROI.pdf). While the user manual includes a set of examples for each function; here we explain the graphical interactive mode. The interactive mode can be launched from an interactive R environment by:
-```{r, echo=TRUE}
+```{r, echo=TRUE, eval=FALSE} 
 
 library(xROI)
 Launch()
 
 ```
 
 or form the command line (e.g. shell in Linux, Terminal in macOS and Command Prompt in Windows machines) where an R engine is already installed by:
-```{shell, echo=TRUE}
+```
 
 Rscript -e “xROI::Launch(Interactive = TRUE)”

 xROI depends on many R packages including: raster, rgdal, sp, jpeg, tiff, shiny, shinyjs, shinyBS, shinyAce, shinyTime, shinyFiles, shinydashboard, shinythemes, colourpicker, rjson, stringr, data.table, lubridate, plotly, moments, and RCurl. All the required libraries and packages will be automatically installed with installation of xROI. The package offers a fully interactive high-level interface as well as a set of low-level functions for ROI processing.
