loading a .RData file into session but no object loaded in Shiny
r, shiny
Solution
The answer is that, whenever an object is used in the `ui.R` and/or `server.R`, the relevant objects must be loaded in the same file. Otherwise, shiny won't know where to find the object from other files (even they're in the same directory and loaded).
Problem
I got my analysis results in R (an object called `obj`) and save it as an .RData file `obj-result.RData`. Now in Shiny, at the beginning of the `ui.R` file, I put `load("obj-results.RData")` so that each time Shiny is run, this object can be loaded into R session, i.e. I expect that the `obj` object would be available to use in subsequent steps, such as `obj@data`, `obj@sample`, etc. However, I find that `load` won't make the `obj` object available in current R session, so that Shiny could not find the quantities required. Is there anything I missed in loading the .RData object? Thank you so much!
