Put 'print' around your variable:
> temp.ttt <- "ttt <- 1\nprint(ttt)"
> conn.ttt <- textConnection(temp.ttt)
> source(conn.ttt, echo=TRUE) ## name of variable is echoed
> ttt <- 1
> print(ttt)
[1] 1
> close(conn.ttt)
> cat(file="c:/temp/temp.R", temp.ttt) ## name of variable not echoed
> source("c:/temp/temp.R", echo=TRUE)
> ttt <- 1
> print(ttt)
[1] 1

> temp.abc <- "abc <- 1\nprint(abc)"
> conn.abc <- textConnection(temp.abc)
> source(conn.abc, echo=TRUE) ## name of variable is echoed
> abc <- 1
> print(abc)
[1] 1
> close(conn.abc)
> cat(file="c:/temp/temp.R", temp.abc) ## name of variable is echoed
> source("c:/temp/temp.R", echo=TRUE)
> abc <- 1
> print(abc)
[1] 1
