You can do that with ls and the pattern= argument. For example,
ls(pattern = "my")
finds all objects with my anywhere in the name. See ?ls

John wallace called lsx()

: Reason: lsx() allows me to search for object names in my local workspace
matching an unquoted character string.
: Since I forget all the function names or data object names I have added, I
can quickly find any/all names
: matching any specified string.

: BUT: the lsx() function when installed (successfully, no errors reported) in
R does not work in R.
: Why ? Can it be fixed so it can work?

wildcards
