Thanks Duncan. Awesome ideas!
I think we're getting closer!
I tried what you suggested and got a possibly better error...
.
.
.
rConnection.assign("boxMVariable", myDf);
String resultBV = "str(boxMVariable)"; // your suggestion.
RESULTING ERROR:
Error in format.default(nam.ob, width = max(ncn), justify = "left") : invalid
'width' argument
(No idea what this means).
For testing, I'm using the same standard IRIS dataset as the Box's M
documentation shows in biotools:
Examples
data(iris)
boxM(iris[, -5], iris[, 5])
-------
Now, in the debugger, the built values of myDf are these:
myDf = {org.rosuda.REngine.REXPGenericVector@562}
"org.rosuda.REngine.REXPGenericVector@17d99928+[5]”
▼ payload = {org.rosuda.REngine.RList@566} size = 5
► 0 = {org.rosuda.REngine.REXPDouble@570}
"org.rosuda.REngine.REXPDouble@6fffcba5[150]"
► 1 = {org.rosuda.REngine.REXPDouble@571}
"org.rosuda.REngine.REXPDouble@34340fab[150]”
► 2 = {org.rosuda.REngine.REXPDouble@572}
"org.rosuda.REngine.REXPDouble@2aafb23c[150]"
► 3 = {org.rosuda.REngine.REXPDouble@573}
"org.rosuda.REngine.REXPDouble@2b80d80f[150]”
► 4 = {org.rosuda.REngine.REXPString@574}
"org.rosuda.REngine.REXPString@3ab39c39[150]”
Does this help?
Please let me know what else I can try.
