I am trying to assign a title to a tabpanel as "Démarrer" in a shiny application. But it appears as "Démarrer" in the shiny app.
tabPanle(titele = "Démarrer")
Does anyone know how to get it properly in the app as "Démarrer"?
It seems your code file is not in UTF-8. You can try to switch to it using File/Save with encoding).
By the way as a general rule of thumb you can set it as your permanent default encoding by checking the corresponding box in the save with encoding dialog)
Otherwise you might try to use HTML entities to code your accents (remove the space between & and eacute;).
tabPanel(title=HTML("D& eacute;marrer"))

I am new to R and Rmd and trying to generate a report using Rmd. This report has several images inserted along with the text. I am able to insert an image by hardcoding the path of the image. I have no problems with that but I need the path as a variable because it varies with the project. Can anyone help me with the syntax for calling a variable within a path to the image?
"Project123" changes based on the project. Is there a way I can declare this variable and call it to define the path?
Help please.
Images can use online R code for dynamic paths and/or alt text. (Early adopters of rmarkdown often tried this method as the default method of including R plots in the reports, using png(filepath...); plot(...); dev.off() followed by what I recommend you use.)
This will allow you to do what you need:
as raw markdown (and not inside a traditional code chunk).
If you aren't familiar with inline code blocks, then know that you can put just about anything in an inline code block. This is handy for including dynamic content in a paragraph of text, for example "the variance of the sample is \r var(sample(99))``". (Often it is just a pre-created variable, if numeric it is often rounded or formated to control the display of significant figures.)
In R (just default mac R) on my mac machine, when I see the help page with
> ?read.csv
it appears on a new window with a beautiful format.
Now I'm using the Sublime text 3 for R (with SublimeREPL:R, R-Box, R-Extended etc.) on the mac machine, many things work fine.
My question is:
when I type the help page (?read.csv), the contents appear on the same ST3 window with a plain format.
Is there any way to make it appear on a new window such as a HTML page (in Safari)?
Set the help_type option to "html":
options(help_type = 'html')
and it will open help files in the default browser. If you put that in your .Rprofile, you won't need to set it for each session.
Rstudio changed how a code section is defined. In version 0.99.902 code sections had to have some text behind the hash symbol. But now in version 1.0.136 if there are 5 hashes in a row it will define a new section.
Is there anyway to make it go back to the old way of defining sections? It isn't a big deal except I would mark my sections with hashes above and below the name and now it is creating 3x as many sections.
Old version:
New version:
I don't know if there's a way to recover the old behavior, but you could use + instead. In addition, you can put this in a code snippet (if you haven't already). In Preferences, go to the Code tab, scroll to the bottom and click the Edit Snippets button. Then add something like the following:
snippet hd
`r "# ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
### HEAD ##########
# ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++"`
Then, when you type hd followed by a tab (actually two tabs, since the first tab will bring up a few options that start with hd, but hd will be at the top, so you can just press tab twice) in your R script file, the following will appear:
# ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
### HEAD ##########
# ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Better yet, you can create a snippet that takes the heading text as an argument:
snippet hd
`r paste("# ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++\n",
"### ", "${1:HEAD}", " ##########\n",
"# ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++", sep="")`
Then, when you type hd followed by two tabs, the HEAD text will be highlighted and you can just type in your actual heading text.
Unfortunately, this behavior has changed between RStudio v0.98.1091, v0.99.903 and the current release v1.0.136.
In RStudio v0.98.1091, 'empty' headers such as ##### were recognized as section headers.
This behavior was briefly changed with v0.99.903, such that some initial text was required for these to be recognized as section headers. A number of users were unhappy as this effectively broke code folding for users who were explicitly using standalone ##### blocks to create sections.
Because of that, the behavior was reverted in RStudio v1.0.136, and so now standalone ##### blocks are again recognized as section headers.
Using Rstudio [Windows8], when I use the dygraph function to plot a time series, I have a problem when trying to use UTF-8 characters in the main title.
library(dygraphs)
dygraph(AirPassengers, main = "Título")
This results in a title: "T?tulo"
I have tried to convert "Título" to the utf-8 enconding, but it doesn't work.
You can use enc2utf8.
dygraph(AirPassengers, main = enc2utf8("Título"))
You need to make sure your locale settings support the character that you want to use, and that the file is saved with the right encoding. Saving as UTF-8 worked for me.
I was able to replicate your situation in Windows 7 and tried a bunch of things. Embedded in Rmarkdown, here is a minimal working example.
```{r}
Sys.setlocale("LC_ALL","German")
#note that windows locale names are different from unix & mac, usually
#the name of nationality works here.
#also works with "Faroese", "Hungarian", and others who have this letter.
#the locale has to be set in a preceding block to take effect.
```
```{r}
Encoding("Título")
library(dygraphs)
dygraph(AirPassengers, main = "Título")
```
You can try out the encoding given to the title to have with Encoding(). Languages like Faroese, Hungarian, and German encode "Título" as latin or unknown, both of which seem to cause no problems for dygraph's javascript. UTF-8 wrote it as <U+00ED> which was a problem for the javascript, as well as some, but not all other functions. With a matching locale, converting to utf-8 as #Michele recommended has the same result.
Also, if you don't have the title in many places, it is possible to just manually find and replace the title in the html/javascript file that is made. The problem occurs on conversion, but if the file is already made, the title variable can be successfully changed. The letter still has a question mark in Rstudio "Viewer" output, but I recommend making the entire file for javascript regularly, as I've seen other functions malfunction in the viewer window.
I want to pass data from Spotfire to R and then display the plot constructed by R.
What is the best way to do this?
I’ve figured out the trick of putting images into Spotfire. It’s not hard if you follow these directions, but it’s done in a way very different from how you guess you would do it in Spotfire, and that’s why it took me awhile to figure out.
Here’s an overview of how to do it. You create a DocumentProperty which is a binary object, you write some Spotfire code that gives a value to that Document Property, and you display that binary object using a Spotfire Property Control of the “Label” type.
The confusing parts are that you DON’T use the Spotfire “Insert Image” tool at all, and that you DON’T use the filename generated inside the R code in Spotfire at all. Once you get used to the idea that the two most obvious ways you think you would approach the problem in Spotfire are entirely useless and wrong, you can make some progress.
I’ll leave out the spiderplot specifics because the code’s pretty long.
Here’s what you do.
1) Create a document Property in Spotfire of type “Binary”, e.g., “imageThatGoesBackToSpotfire”
2) You write some R code that generates an image and writes it to a file:
# get a temporary directory name on the local machine. You wouldn’t need to do this is you were just
# going to run it on your own, but you need to do it if you intend to let anybody else run it on their own machine.
tempfilebase = tempfile()
# take the tempfilebase and prepend it to a filename.
myFilename<-“someFileName.jpg”
myFullFilename <- paste(tempfilebase,myFilename,sep="")
#open a jpeg
jpeg(filename=myFullFileName)
# generate the image, however you normally would in R
plot(input)
# close the file
dev.off
# open a connection to that file.
myConnection<-file(myFullFileName,open=”rb”)
imageThatGoesBackToSpotfire<- data.frame(r=readBin(myConnection, what="raw", n=(file.info(myFullFileName)$size)))
close(myConnection)
3) Run your R script, above. Select some columns that are the “input” to the plot, and make the R script return outputs to the “imageThatGoesBackToSpotfire” DocumentProperties.
4) Create a text area in Spotfire.
5) Insert a Property Control into the text area of type “label”. (Click on the icon that’s circled in the picture below). This opens a dialog,
You need to register a data function with inputs and outputs, and the specific PNG data needs to be returned as a binary label.
