[Qgis-user] import vector layer in manageR

[Paulo van Breugel]

Hi Sebastiano

Thanks for the suggestion. Both are great tools, but I would use them 
for different kind of tasks.

What I like about manageR is that it is basically an alternative CLI 
(including syntax highlighting) combined with a simple GUI with some 
predefined R relevant functions and with a loose integration of R in 
QGIS (easy import/export of data between the two).

I like the Sextante plugin too, but it serves a different purpose (for 
me). The R module does not seem to be a direct access to the R command 
line (or at least I haven't found out how). This means it only gives 
access to predefined functions or you have to create functions yourself 
which can then be access through a GUI window. This is extremely useful 
when working often with certain R functions, but without the option to 
work directly from the command line and direct access to all R functions 
(without having to define functions first), it does not offer the same 
flexibility that manageR offers.

Cheers,

Paulo
