shiny issue after app update #151

Open umasaxena opened 4 years ago

umasaxena commented 4 years ago

I updated my shiny app (the first time worked), then started getting the weird filepath error - To give a little bit of the background. I am reading in rds file where a gene list act as input to search through mongodb database.

Any help is appreciated.

It goes like this;

cc=readRDS("./CC.rds") gg=readRDS("./GG.rds") ss=readRDS("./SS.rds")

ui.R

selectizeInput("epiInput","Gene", choices=gg), selectizeInput("cellInput","Tissue", choices=cc), selectizeInput("anygene","Any Gene", choices=ss), helpText("Note: Select gene and cell line tissue of interest"), actionButton("Search", "search")

Error:

runApp() Error in readRDS(nsInfoFilePath) : error reading from connection

The backtrace is given below. I just dont know how to correlate the bactrace output to the error to identify where its occuring.

It looks to me like the crosstalk library has gotten corrupted somehow. Is it possible you installed crosstalk using an older version of R than you are now running? Can you try uninstalling and reinstalling crosstalk, and see if that helps--either to make the app run or at least to get the backtrace to change?

Thanks. It required mainly C libraries update and Rcpp. Crosstalk worked file on clean re-install.
