Hi,
Try this:
f1<- function(name)
{
env <- list2env(list(mgkg = bquote(mg ~ kg^{-1}),
ugkg = bquote(mu * g ~ kg^{-1})),
parent = emptyenv())
pattern <- paste0("(", paste(objects(env), collapse="|"), ")")
bquoteExpr<-parse(text=gsub("_"," ",gsub(pattern,"~(.(\\1))~",name)))[[1]]
do.call(bquote, list(bquoteExpr, env))
}
sapply(DATA_names,f1)
$A_ugkg_FA
A ~ (mu * g ~ kg^{
-1
}) ~ FA
$S_mgkg_XRF
S ~ (mg ~ kg^{
-1
}) ~ XRF
$Cl_mgkg_XR
Cl ~ (mg ~ kg^{
-1
}) ~ XR
A.K.

Initially, I wanted to remove the suffixes, but now I want to end up with the
following
c("A_ugkg_FA","S_mgkg_XRF" ,"Cl_mgkg_XR")
-1
A (ug kg ) FA
-1
S (mg kg ) XRF
-1
Cl (mg kg ) XR
Thanks all
