Hello,

When I add the following command to my trackViewer Vignette:

setTrackXscaleParam(trackList[[1]], attr="position", 
                    value=list(x=122929700, y=3, label=200))

R gives me the following error:

Error in setTrackXscaleParam(trackList[[1]], attr = "position", value = list(x = 122929700, : attr must be a slot name of xscale object
3.
stop("attr must be a slot name of xscale object")
2.
setTrackXscaleParam(trackList[[1]], attr = "position", value = list(x = 122929700, y = 3, label = 200))
1.
setTrackXscaleParam(trackList[[1]], attr = "position", value = list(x = 122929700, y = 3, label = 200))

Is there something that I did wrong? Thanks!

I'll post sessionInfo() and my code below.

Hi Iiruiradiant,

Thank you for reporting this. Could you try following code to see if there is any issue with your installation:

showMethods("setTrackXscaleParam", includeDefs = TRUE)

And also try


---
title: "test"
output: html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)

```{r }
library(trackViewer)
sessionInfo()

To see if there is any difference when you compile the Rmd file.

Jianhong.
