MODISTsp Installation

[lbusett]

Hi Effie,

can you please try this:

1. Remove packages "gWidgets", "gWidgetsRGtk2" and "RGtk2" using remove.packages or from RStudio
2. Remove package MODIStsp in the same way
3. update.packages()
4. Close and reopen RStudio
5. install.packages("gWidgetsRGtk2"). Install GTK+ when asked - kill RStudio if necessary
6. reopen RStudio
7. library(gWidgetsRGtk2)

if gWidgetsRGtk2 loads correctly, then you should be ok and you can retry MODIStsp installations.

Otherwise please reply to this with the error message you get.

Hi Lorenzo,
thank you so much for the immediate response. The error message reads:

library("gWidgetsRGtk2", lib.loc="D:/R-3.2.3/R-3.3.3/library")

Learn more about GTK+ at http://www.gtk.org
If the package still does not load, please ensure that GTK+ is installed and that it is on your PATH environment variable
IN ANY CASE, RESTART R BEFORE TRYING TO LOAD THE PACKAGE AGAIN

Warning messages:

GTK+ indeed exists, and the path is updated.

ok. What happens if you now close and reopen RStudio and try to load gWidgetsRGtk again ?

[effie-pav]

The packages are loading, but MODIStsp installation is interrupted at
*** arch -i386
With the message:
The procedure entry point deflateSetHeader could not be located in the dynamic link library zlib1.dll

The same happens when I load gWidgets2RGtk. I do close/reopen R, and the system as well.Do you think this has to do with the package and its dependencies, or with the architecture of the installation? (Would it help uninstalling and reinstalling R from scratch?)
Thank you again for the support..!

[lbusett]

ok... that's slightly different from what happens usually.

Can you try to follow instructions reported here:

https://www.stat.auckland.ac.nz/%7Ekimihia/rgtk2

, starting from "Download the GTK+ all-in-one bundle. I downloaded version 2.22 for Windows 64-bit."
?

[effie-pav]

Yes!, it worked very nicely. The page you referred to is very useful. The only thing not working was the link to the bundle. I downloaded the GTK+ bundle from http://www.tarnyko.net/dl/gtk.htm (apparently my system had issues with the GTK+ Windows Runtime Environment Installers).
To successfully install MODISTsp I also had to manually (re)install the following packages:
foreach, Rcpp, R.utils, stringi, magrittr, and zoo.
Thank you again for the support, and for taking the effort and time to put this tool online-it is great, and much needed!

[lbusett]

Ok, glad that it worked !

By the way: the issue about having to manually install some packages is due to a bug in install_github that can usually be solved by installing the github version of devtools:

On a fresh R session:

devtools::install_github("hadley/devtools")
