[Bioc-devel] package vignette error : external data can't be captured when compiling package vignette

[Jurat Shayidin]

Hi BiocDevel :

I am getting vignette error when I building my packages, and external data
can't be captured by system.file() . I did unit test all function of my
packages, it works fine. When I am going to compile package vignette, test
input bed file can't be detected. However, I used devtools::install()command
to install my packages, but installation directory inst/ was not created
automatically. By R package convention, all external data must be located
in inst/, so I manually created this folder  inst/extdata and paste my
data, but vignette compilation still failed. According to convention of R
package, my package structure will be:

myPackage
`- inst
`- extdata
`- data1.bed
`- data2.bed
`- R
`- ...
`- NAMESPACE
`- DESCRIPTION

-- 

Note that readPeakFile take list of bed file as an input. Here is the toy
function I am going to use in vignette file .

readPeakFile<- function(mydat, ...) {
  files <- list.files(mydat, full.names = TRUE, "\\.bed$")
  readMe <- lapply(files, import.bed)
  return(readMe)}

I got error from this code chunk :

```{r}
library(MSPC)
inputBed <- list.files(system.file("extdata", package = "MSPC"), full.names
= TRUE)
inputData <- readPeakFile(peakFolder = inputBed)

inputData
```

Error: object 'inputData' not found

I tried another way which discussed in mailing list long time ago, but I
got empty list instead :

```{r}
library(MSPC)
extdata.dir <- system.file("extdata", package = "MSPC")
bedfiles <- dir(extdata.dir, pattern="\\.bed$", full.names=TRUE)
myData <- readPeakFiles(peakFolder = bedfiles)

myData
```
named list()

can't figure out why got these issue very often. why installation directory
inst not created automatically ? why test data can't be captured by
system.file() when compiling the package vignette ? I think inst must be
created automatically when I install my packages, but it didn't happen to
me, why is that ? How can I fix this compilation error for package vignette
? Any idea please ?

Here is what I got :
