For instance, the ability to expand or collapse parts of the document (functions can be expanded or collapsed), have code run without output to the console (invisible returns from functions, or assigning function returns to variables).</div><div class=""><br class=""></div><div class="">It doesn’t sound as though this is exactly what you’re looking for—the literate programming concept with rmd documents is very nice—but it might suit your particular needs.</div><div class=""><br class=""></div><div class="">- Tom</div><div><blockquote type="cite" class=""><div class="">On 201604 12, at 10:18, Ivan Calandra <<a href="mailto:ivan.calandra@univ-reims.fr" class="">ivan.calandra@univ-reims.fr</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><span style="font-family: IowanOldStyle-Roman; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; float: none; display: inline !important;" class="">Sorry, I thought it would be clear based on the previous emails...</span><br style="font-family: IowanOldStyle-Roman; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class=""><br style="font-family: IowanOldStyle-Roman; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class=""><span style="font-family: IowanOldStyle-Roman; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; float: none; display: inline !important;" class="">I don't know much yet about chunks and other functionalities of knitr and rmarkdown, so I might be missing some points, but three interesting aspects about chunks that I have already notices is that it is possible to give them names, expand them or reduce them in the script (making the code more readable) and evaluating them but not displaying the results in the html/pdf report. This is possible in RStudio, but it seems that it is not in the R GUI Editor.</span><br style="font-family: IowanOldStyle-Roman; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class=""><br style="font-family: IowanOldStyle-Roman; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class=""><span style="font-family: IowanOldStyle-Roman; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; float: none; display: inline !important;" class="">Ivan</span><br style="font-family: IowanOldStyle-Roman; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class=""></div></blockquote></div><snip></body></html>
