R Improvements for Bio7 2.8

Leave a reply

18.05.2018

The next release of Bio7 adds a lot of new R features and improvements. One minor change is that the default perspective after the startup of Bio7 now is the R perspective to emphazise the importance of R within this software.

The R-Shell view has been simplified and the R templates have been moved in it’s own simple view for an improved usability (see screenshot from R perspective below).

In addition the context menu has been enhanced to allow the creation of submenus from scripts found in folders and subfolders (recursively added) which you can create for a menu structure.
Scripts can be added created in R, JavaScript, Groovy, Jython, BeanShell, ImageJ Macros.
Java (with dependant classes) can be dynamically compiled and executed like a script, too.

Several improvements have also been added to the R-Shell and the R editor for an easier generation of valid R code. The R-Shell and the R editor now display R workspace objects with it’s class and structure in the code completion dialog (marked with a new workspace icon – see below).

R-Shell:

R editor:

In the R editor a new quick fix function has been added to detect and install missing packages (from scanned default packages folder of an R installation – has to be enabled in the Bio7 R code analysis preferences).

Also the detection of missing package imports are fixable (when a function is called but the installed package declaration is missing in the code but the package is installed to deliver the function).

The code assistance in the R-Shell and in the R editor now offers completions for, e.g., dataframes (columns) in the %>% operator of piped function calls:

In addition code assistance is available for list, vectors, dataframes and arrays of named rows and columns, etc., when available in the current R environment.

Code completion for package functions can now easily added with the R-Shell or the R editor which loads the package function help for both interfaces. The editor will automatically be updated (see updated editor marking unknown functions in screencast below).

Numerous other features, improvements and bugfixes have been added, too.

Bio7 2.8 will hopefully be available soon at:

Leave a reply

26.02.2018

Last week I released a new bugfix version of Bio7 which fixes some annoying bugs on MacOSX and updates some plugins.

  • Updated ImageJ to version 1.51v1
  • Improved the import of Java projects (No annoying dialog anymore)
  • Improved the execution of Shiny apps (No dialog when stopping the server)
  • Fixed several bugs and possible deadlocks regarding the swt_awt bridge and the OpenGL panel
  • Fixed a swt_awt key listener bug (ImageJ panel) to restore key events on the panel
  • Fixed a Mac bug in the R editor color dialog (hoover dialog of name R colors)
  • Huge fontsize for Swing (e.g., ImageJ dialogs) can be corrected for Retina displays (Bio7 ImageJ preferences – ‘-6’ for Retina displays fits well)
  • Bio7 editors and the Bio7 Workspace will be automatically saved before application shutdown

Bio7 2.7 Retina-Display Fix for MacOSX

2 Replies

08.01.2018

I recently discovered on a high dpi display (Retina-Display) enabled 13’’ notebook that the latest release of Bio7 for MacOSX is not displayed in high dpi but in a lower resolution which makes text and icons blurry (scaled) and unnecessary strains the eyes when editing R scripts with the R editor.

So I uploaded a new, fixed version for MacOSX.

However, to fix an already downloaded version of Bio7 you have to open open the ‘/Bio7.app/Contents/Info.plist’ file with a text editor (right-click on Bio7.app, execute ‘Show Package Contents’ and open ‘/Contents/Info.plist’) and add the following lines before the </dict> tag:

<key>NSHighResolutionCapable</key>
<true/>

In addition to update the Info.plist file for the Operating System you have to open the Terminal (in ‘Applications/Utilities’) and execute the following command (default install directory – shell command is one line!):

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -v -f /Applications/Bio7.app

Here some screenshots from before and after the fix was applied on a Retina-Display (zoom in for details):
