Problem getting plots of projections into R with rggobi

[Raphael Rath]

Hello,

I have troubles getting nice looking plots of projections into R:

First I tried to get the olive dataset into R:

>o <- ggobi(ggobi_find_file("data", "olives.csv"))

** (rsession.exe:7804): CRITICAL **: datad_init: assertion `d->nrows > 0' failed   

After that I managed to get it into R like this but it dosent look the same as if I open the dataset in Ggobi with file->open:

olive <- read.table("C:\\Program Files\\ggobi\\data\\olive.csv", header=T, sep=",")

olive <- olive[,-1]

o <-ggobi(olive)

In the next step I wanted to get some projections from a 1D and 2D Tour into R using ggobi_display_get_tour_projection after pausing the projection and i get an error again

display(o[1], "2D Tour")   

ggobi_display_get_tour_projection(o)

** (rsession.exe:7804): CRITICAL **: An R GGobi display object must inherit from class 'GGobiDisplay'

** (rsession.exe:7804): CRITICAL **: RS_GGOBI_getPModeName: assertion `GGOBI_IS_DISPLAY(display)' failed

** (rsession.exe:7804): CRITICAL **: An R GGobi display object must inherit from class 'GGobiDisplay'

Error in .GGobiCall("getTourProjection", gd, pmode(gd)) : 

  CHAR() can only be applied to a 'CHARSXP', not a 'NULL'

Because this did not work I just saved the projections with Save Display Description and read it into R with dd_load. This worked but then there was another problem: The legend covers some of the points and I did not find a way to move it to another postion.

(I tried to attach this file to this post but it says that it is inadmissible)

Hole <- dd_load("...path...\\1DHoles")

plot(Hole)

I also tried print(ggplot(Hole)) which didnt looked better.

Finally my last question: Is it possible to plot a Spineplot in R from a file that I saved with Save Display Description, because in the R-Help it says that this feature is not yet implemented?

Thanks a lot and I apologize for any spelling mistakes, my english is not very good... 

Best regards,

Raphael

I now managed to attach the 1DHole file to this mail.

plot(d, axislocation=c(0.8, 0.8))

allows you to set the location of the axes. 

can’t get this to work with the ggplot function, though, only the plot function.
