R help - Mar 2010 - Put square brackets as column name in a data frame

Hi everyone,

this is a pretty simple question, but I have not found any answer about this
in this forum.

I'm trying to make a data frame like this :

ID,X[m],Y[m],Z[m]
0,-4.32902,-3.5437,12.4441
1,-4.31887,-3.54278,12.4441
2,-4.33672,-3.54401,12.4615
3,-4.67554,-2.78566,13.4151
4,-4.71124,-2.79889,13.4204
...

Actually, with my code, I'm getting this :

ID,X.m.,Y.m.,Z.m.
0,-4.32902,-3.5437,12.4441
1,-4.31887,-3.54278,12.4441
2,-4.33672,-3.54401,12.4615
3,-4.67554,-2.78566,13.4151
4,-4.71124,-2.79889,13.4204
...

How can I put square brackets ([ ]) in column names?

this is my code :

nouvTable <-
data.frame(ID=0:longueur,X[m]=colonneX,Y[m]=colonneY,Z[m]=colonneZ)

After, I'm putting this data frame in a text file

write.table(nouvTable, file = "C:/....txt",
sep=",",quote=FALSE,row.names FALSE)

Everything work fine but I need the correct column names  

Thank you

names(nouvTable) =
c("ID","X[m]","Y[m]","Z[m]")

  Or read the table with check.names=FALSE .
  Note that this can lead to later hassles with referencing the columns;
for example you would need nouvTable$`X[m]` rather than nouvTable$X[m]
