Replace all words in a sentence starting with dollar signs-CodePudding

I want to replace all elements of a string starting with a dollar sign. Here you can find my example:

my_string <- "$AAPL $TSLA I recomend to buy $TLSA and to sell $AAPL; the price is rising to $12.56"

The replacement is the word "cashtag".
Here is my desired output:

my_string
"cashtag cashtag I recomend to buy cashtag and to sell cashtag; the price is rising to $12.56"

I already tried it with str_replace_all and startsWith.
But so far I have not come to a solution.
I would also be very happy about a suggested solution using the tidyverse package.

note than in a regex in R, you'll have to escape the $ with a backslash, and then you'll have to escape this backslash with another backslash ;)

stringr::str_replace_all(my_string, "\\$[A-Z] ", "cashtag")
[1] "cashtag cashtag I recomend to buy cashtag and to sell cashtag; the price is rising to $12.56"

Using gsub:

gsub("\\$[A-Z] ", "cashtag", my_string)
# [1] "cashtag cashtag I recomend to buy cashtag and to sell cashtag; the price is rising to $12.56"
