tclarray with embedded spaces in data

I would like to use a tclArray: mytkarray <- tclArray() as the variable for a table: table1 <- tkwidget(f1, 'table', variable= mytkarray) but if I include character strings with embedded spaces, I get braces appearing in the table. I can remove them using a non-R tclarray, (the difference between the first example of http://www.sciviews.org/_rgui/tcltk/Tktable.html and http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/tktable.html - the result of the second of which includes the braces (although not in the image provided!) and that of the first does not - but this seems undesirably complicated. Am I missing something simple? Any insights would be gratefully received,

This is a right-honourable pain with Tcl, and it took me quite some time
to reconstruct what I did several years ago on this matter. The short
answer is that you need to assign things like
as.tclObj("foo bar baz", drop=TRUE)
into your array. The longer story involves the ambiguity in Tcl between
lists of words separated by whitespace and strings with spaces inside. I
suspect that the sciviews approach doesn't actually cover all cases,
paste()'ing raw tcl commands together usually leaves you burning in
Quoting Hell.
