Question about memory allocation error

["Brian Wu" <bwu@guzman.com>]

My program did lots ODBC querys.

It works at the first run and always show error at the second (sometime third) run.

I put those lines into a function and call the function. The following error still show up in the second or third run.

Any clue of this problem?

Any suggestion will be greatly apprecitated.

 

********************** Error Message******************

Error in odbcQuery(channel, query, rows_at_time) :

In addition: Warning message:

Subject: [S] guiPlot question

 

Dear members,

 

I have question related to guiPlot called within a function.

 

The following example works fine:

my.variables <- data.frame(runif(10), runif(10), runif(10))

 

guiPlot("3D Scatter", DataSetValues = my.variables)
guiModify("Axes3D", Name = "1", xTitleText = "Name of variable 1", yTitleText = "Name of variable 2", zTitleText = "Name of variable 3")
guiCreate("MainTitle", Name = "1", Title = "3D Scatter Plot")

 

 

However, if I define the function:

plot.function <- function(my.data) {
 guiPlot("3D Scatter", DataSetValues = my.data)
 guiModify("Axes3D", Name = "1", xTitleText = names(my.data)[1], yTitleText = names(my.data)[2], zTitleText = names(my.data)[3])
 guiCreate("MainTitle", Name = "1", Title = "3D Scatter Plot")
 guiCreate("Grid3D", Name = guiGetPlotName(), ProjectionPlane = "XY", Position = "0.0")
}

 

And, rename the variables

names(my.variables) <- c( "Name of variable 1",  "Name of variable 2",  "Name of variable 3")

 

The following command:
plot.function(my.variables)

gives the error:

Problem in guiPlot("3D Scatter", DataSetValues = my.data): A name is required in order to assign an object to a database

 

I don't know what this error means. I'd appreciate any help on this subject.

 

Thanks in advance.

 

Eric
