I have written a simple script to create some PowerPoint sheets based on an Excel dataset. For the original script see Picture1. I noticed that the code becomes very unreadable if you add to many objects to one PowerPoint sheet. That's why I wanted to write a function of this part of the code. One of the things I tried is shown in Picture 2 (I know this code won't work). The problem is that the function doesn't recognize ph_with. Is there anyway to solve this problem?
Thank you!
AddContent <- function(content, label, ...){
ph_with(value = content, location = ph_location_label(ph_label = label))}
AddContent(company_name, Customername)
Error in UseMethod("ph_with", value) : no applicable method for 'ph_with' applied to an object of class "rpptx"

When I try to generate the exams' solution with the exams2nops(...template="solution"...) I get the following error message:
Error in exams2pdf(file, n = n, nsamp = nsamp, dir = dir, name = name, :
formal argument "template" matched by multiple actual arguments
How can I produce an exams' solution with the exams2nops?
You cannot do that in one go, you need two runs after setting the same seed, e.g.,
set.seed(1)
exams2nops(my_exam)
set.seed(1)
exams2pdf(my_exam, template = "my_solution.tex")
You can use the solution.tex provided within the package as a starting point for my_solution.tex. But you may want to translate it to your natural language, use the name of your university, possibly insert a logo, add your actual exam name, possibly some into text etc. In exams2pdf() you need to add these things in the template LaTeX file directly.
won't the template="solution" not work in the exams2pdf? Also, can we do something like:
usepackage = "pdfpages", intro = intro2,... ?
I am using blogdown to to create a blogpost that has a series of tables. Creating a single table using the kable function works fine. If you do
blogdown::new_site()
blogdown::new_post("test", ext = ".rmd")
A new rmd file will be created within the content/post directory of the project. If you open that file and create a single table by doing
```{r test1}
library(knitr)
library(magrittr)
library(shiny)
data.frame(a= c(1,2,3)) %>% kable(caption = 'test',format = 'html')
```
A correctly formatted table will be generated. The caption will read "
Table 1: test" If you look at the code of the generated site, the caption will look like this.
<caption>
<span id="tab:test1">Table 1: </span>test
</caption>
Ideally I don't have any desire to label the table as Table 1 in the first place but that is another question. If formatting of captions by kable can be disabled entirely, I'd also be happy.
However if I use lapply to generate 2 tables instead
```{r test2}
lapply(1:2,function(x){
data.frame(a= c(1,2,3)) %>% kable(caption = 'test2',format = 'html') %>% HTML()
}) -> tables
tables[[1]]
tables[[2]]
```
The captions will have the prefix \#tab:test2. If you look at the caption of these tables, you'll see
<caption>(\#tab:test2)test2</caption>
The question is, why kable behaves differently when its called from a lapply compared to its behaviour outside? Note that both of these behaviours are different that its behaviour when simply knitting the file as an html_document.
I did some digging into the kable's code and found that the caption link is created by the knitr:::create_label function. Looking into this function, I saw the part that is responsible for the wrong behaviour seen with the multiple tables.
if (isTRUE(opts_knit$get("bookdown.internal.label"))) {
lab1 = "(\\#"
lab2 = ")"
}
I could not find the code, responsible for the "correct" behaviour with the single table but it seems like knitr internal options are responsible.
Ultimately the behaviour that I want is simply
<caption>test</caption>
which is the behaviour when simply knitting an html document. But I am yet to find a way to set the relevant knitr options and why are they different within the same document.
Edit: Further examination suggests that the issue isn't lapply specific. It can be replicated using a for loop or even { by itself. A complete post with all the problematic examples can be acquired from this issue on knitr's github page. This github repo includes the basic blogdown site that replicates the issue
Turns out the responsible party is not the lapply call but the HTML call at the end. It seems like the regular process by knitr in blogdown and bookdown is to have a temporary marker for the table references in the form of (\#tab:label) and replace it with the appropriate syntax later in the processing.
I was using the HTML call to be able to use the tags object in shiny/htmltools to bind the tables together. This approach seems to make the process of replacing the temporary marker impossible for reasons outside my understanding. For my own purposes I was able to remove the temporary marker all together to get rid of both malformed captions and the working-as-intended table numbers by doing
remove_table_numbers = function(table){
old_attributes = attributes(table)
table %<>% as.character() %>% gsub("\\(\\\\#tab:.*?\\)","",.)
attributes(table) = old_attributes
return(table)
}
data.frame(a= c(1,2,3)) %>% kable(caption = 'test',format = 'html') %>% remove_table_numbers
This question still would benefit from a proper explanation of the reference link placement process and if its possible to apply it to tables in HTML calls as well. But for know this solves my issue. I'll gladly switch the accepted answer if a more complete explanation appears
I am doing java and R integration using JRI.
Please find below script
String path = "C:\\Users\\hrpatel\\Desktop\\CSVs\\DataNVOCT.csv";
rengine.eval("library(tseries)");
rengine.eval(String.format("mydata <- read.csv('%s')",path.replace('\\', '/')));
String exportFilePath= "C:\\Users\\hrpatel\\Desktop\\CSVs\\arima3.jpg";
rengine.eval("Y <- NewVisits");
rengine.eval("t <- Day.Index");
rengine.eval("summary(Y)");
rengine.eval("adf.test(Y, alternative='stationary')");
rengine.eval("adf.test(Y, alternative='stationary', k=0)");
rengine.eval("acf(Y)");
rengine.eval("pacf(Y)");
rengine.eval("mydata.arima101 <- arima(Y,order=c(1,0,1))");
rengine.eval("mydata.pred1 <- predict(mydata.arima101, n.ahead=1000)");
rengine.eval(String.format("jpeg('%s')",exportFilePath.replace('\\', '/')));
rengine.eval("plot(t,Y)");
rengine.eval("lines(mydata.pred1$pred, col='blue',size=10)");
rengine.eval("lines(mydata.pred1$pred+1*mydata.pred1$se, col='red')");
rengine.eval("lines(mydata.pred1$pred-1*mydata.pred1$se, col='red')");
rengine.eval("dev.off()");
In above codebase when i tried plot(t,Y) or plot(Y). it export a blank image, while in case of plot(mydata) it is working file.
One more thing when i run above code in R it creates the image(using JRI it shows blank image).
I have spend 1 day to solve this but i dont found any solution.
Please suggest if you have any alternatives.
Your help is needed.
Thanks in Advance
if i understand correctly, you have a data set named mydata, that has two columns, NewVisits, and Day.Index, in that case you need to change:
rengine.eval("Y <- NewVisits");
to
rengine.eval("Y <- mydata$NewVisits");
and
rengine.eval("t <- Day.Index");
to
rengine.eval("t <- mydata$Day.Index");
This also explains why plot(mydata) works for you - because R recognizes it.
if this isn't the solution, then i cant see where you are reading NewVisits and Day.Index from
BTW i stongly recommend to plot using the ggplot package
I am using tableNominal{reporttools} to produce frequency tables. The way I understand it, tableNominal() produces latex code which has to be copied and pasted onto a text file and then saved as .tex. But is it possible to simple export the table produced as can be done in print(xtable(table), file="path/outfile.tex"))?
You may be able to use either latex or latexTranslate from the "Hmisc" package for this purpose. If you have the necessary program infrastructure the output gets sent to your TeX engine. (You may be able to improve the level of our answers by adding specific examples.)
Looks like that function does not return a character vector, so you need to use a strategy to capture the output from cat(). Using the example in the help page:
capture.output( TN <- tableNominal(vars = vars, weights = weights, group = group,
cap = "Table of nominal variables.", lab = "tab: nominal") ,
file="outfile.tex")
I am trying to use the xlsx package to fill a spreadsheet with information from an external file. Up until now, I have used addDataFrame() to put information into the spreadsheet, and everything about it that I have tried has been successful (fonts, colors, borders, etc.)
The issue now is that I need to have a column of hyperlinks, and to do that I need to get or create the specific cells (I'm not sure which, and both give the same error). The following code:
library(xlsx)
wb = createWorkbook(type="xlsx")
sheet = createSheet(wb, sheetName="InProduction")
createCell(1, 2)
Produces the error:
Error in .jcall(row[[ir]], "Lorg/apache/poi/ss/usermodel/Cell;",
"createCell", : RcallMethod: cannot determine object class
After doing some poking around, I found the method it is trying to call is from this API with the call:
minColIx <- .jcall(row[[ir]], "T", "getFirstCellNum")
Which seems to me like it ought to work, but it clearly doesn't. Can anyone shed some light on this?
Thanks in advance!
You need to create rows using createRow or getRows before you can create cells in these rows using createCells.
