EViews 10 offers important interface improvements, highlighted by a new, full-featured snapshot backup system for your workfiles.
Workfile Backup Snapshots
EViews 10 offers a new workfile backup feature, which we term “snapshots.” The snapshot system may be used to save the current state of the workfile, to roll back a workfile to a prior state, or to investigate the changes made to your workfile between different vintages.
You may configure EViews to automatically take snapshots at periodic intervals, and snapshots may also be taken manually whenever you want to save the current state of the workfile.
You may use the snapshot system to display properties of your backups and to revert to a particular version of your data:
See “Snapshot Backups” for additional detail.
See also the command wfsnapshot
Enhanced Logging Abilities
EViews 10 offers enhanced control over your log and message windows. EViews 10 now allows all program log windows to appear as tabbed windows, and you may rearrange positions of each window. Additionally, you have the ability to specify a name for the log window and direct the messages to the log window with the specified name. If no name is specified, the messages are directed to a window with the name of the program. This was the default behavior in previous versions of EViews.
EViews 10 expands considerably your control over these windows. You may now direct messages to specific windows, appending or clearing any existing content. You may save logs to a text file or freeze the log into a text object. All of these actions can be accessed by a popup menu that appears when right-clicking on a message log window.
Once created, the log windows appear as tabbed windows and can be rearranged by the user as desired.
There are several types of messages which can be logged: program lines, status line messages, user log messages, and program errors. When displayed in a log message, each type will appear in a different color, making it easier to differentiate one type from another.

Live Statistics Display
The series and group spreadsheet views now display interactive statistics. When a spreadsheet is first opened the statistics are computed using all of the data in the spreadsheet.
Double-clicking on the bottom bar brings up a menu where the statistics shown can be changed. A maximum of six statistics may be displayed at once.
The statistics are recalculated every time a group of cells is highlighted.
The statistics displayed can also be set by going to Options/General Options... from the main menu and then the Spreadsheets/Live statistics page.
Long Object Names
EViews 10 increases the maximum object name length from 24 to 300 characters.
Note: you may experience difficulties when trying to open a workfile with object names longer than 24 characters in previous versions of EViews.
Improved R Connectivity
Previous versions of EViews connected to R through a third-party program. We found that some users encountered difficulty in configuring this software to work in their computing environment.
EViews now supports R integration directly, eliminating the need for third-party software. Simply install both EViews 10 and R on the same computer (EViews was developed and tested with R version 3.2.3. You must have version 3.2.3 or newer installed on the machine running EViews).
Installing R
EViews was developed and tested with R version 3.2.3. You must have version 3.2.3 or newer installed on the machine running EViews.
If you do not currently have R installed, simply go to the following site and download the latest version:
https://cran.r-project.org
Verifying EViews R Connector
Verify that the new EViews R Connector Interface components are properly registered by running the EViews command REGCOMPONENTS:
In the Register Components dialog, make sure that the EViews R Connector Interface objects have been properly registered. If not, click the Yes (All) button to re-register these components on your local machine, then re-run REGCOMPONENTS to verify the registration. Note: Registration of these components will require local administrator rights. If you do not have these admin rights, please contact your IT department for support.
Next, go to the External Program Interface dialog under the Options menu/General Options/External Program Interface:
In COM ProgID group, make sure that EViewsRConn.VariantRConn is selected for R.
Next, if Home Path is blank, click the […] button and navigate to your local R installation. Select the version-specific R folder (e.g., “R-3.2.3”) under the parent R folder as your home directory.
Optionally, you can also select your Save Series as preference when pushing EViews series objects into R. If you select “ts (time series)”, series objects that have a compatible R ts frequency will be pushed as R ts objects. Otherwise, an R data.frame structure will be created instead.
Now we're ready to begin using R.
