I was previously using quantsrat_0.9.1739 & blotter_0.9.1741 for some time and it worked fine until I updated them to the latest version 0.10.7 with blotter 0.12.4.
Most of the simulations that I previously wrote throw in the following message:
(This one has been extracted from the demo(macd))
Warning message:
In .updatePosPL(Portfolio = pname, Symbol = as.character(symbol), :
Could not parse ::2018-01-12 as ISO8601 string, or one/bothends of the range were outside the available prices: 2007-01-03/2014-05-30. Using all data instead.
It modifies the end results of nearly 50% of the backtest I generated in the past.
If I go back to the previous version of quantstrat and run the same strategies everything goes back to normal.
I would appreciate if anyone who might have faced the same situation as me could let me know how this problem can be fixed.
Here is more info regarding my session:

I recently installed pandoc 2.4 on Windows and the conversion failed with error 1 occurs for all knitting. I can't knit html, word, and pdf.
The error says
output file: template.knitmd
pandoc.exe: template.utf8.md: openBinaryFile: does not exist (No such file or directory)
Error: pandoc document conversion failed with error 1
Execusion halted
This happens to even the raw basic template rmd file.
I am using a closed network without internet connection and limited writing permission. Previously I was able to knit rmd files located in documents folder generating outputs in same location.

Any advice will be highly appreciated. (Or even ways how to change the settings back to old pandoc version without deleting the version 2.4.)
I have had this issue as well. Mapping the network drive where my R project was stored by following the instructions here solved the issue for me.
I change my system language to English both:
1) In R, R console: language = en
2) For any R script file : Sys.setlocale(category = "LC_ALL", locale = "english")
But when I started a new R markdown file in R Studio, the date is still not in English.
Anyone can help solve this issue? Thank you.

Most of the time I have issues visualizing the preview inline in Rstudio notebook. The problem is that the output of the chunks remains fixed in the screen.
I didnt change the configuration.
Is this a bug or is normal for rstudio notebook?

I have one Ubuntu14.04 laptops,
when I run below with RStudio Viewer, it work fines.
> library(dygraphs)
> dygraph(ldeaths, main = "All", group = "lung-deaths")
After I set below options to run in external browser,
options("viewer"=NULL)
dygraph(ldeaths, main = "All", group = "lung-deaths")
The browser will open files with below URL but nothing show:
http://localhost:18186/session/viewhtmla4c45554fcb/index.html
If I do the same thing in R console
library(dygraphs)
dygraph(ldeaths, main = "All", group = "lung-deaths")
it work fine and will open with URL with file:///tmp/RtmpE7nROm/viewhtmlf371b65fc2c/index.html
Questions1: Why Rstudio will open "http://localhost:18186..." instead of "file://....."?
Questions2: What commands in Rstudio to revert the display show in Viewer again? Currently I have to quit Rstudio and restart to get show in Viewer again.
PS: I doesn't see this issue in another Linux Labtops, not sure what configuration will causing this, hope someone can help to answer!
