[R] xyplot: problems with column names & legend

[baptiste auguie]

Hi,

Using backticks might work to some extent,

library(lattice)
`my variable` = 1:10
y=rnorm(10)
xyplot(`my variable` ~ y)

but if your data is in a data.frame the names should have been converted,

make.names('my variable')
[1] "my.variable"


HTH,
