What's Changed

• Fix: memory leak on converting POSIXlt to q
• Fix: Rset could crash if first param not char/string/sym
• Updated docs
• 1 item value from R converted to q atom instead of 1 item list
• Rfunc for calling r function with q parameters. See https://github.com/KxSystems/embedR/blob/master/docs/README.md for details e.g. calling r paste function to concatenate 2 strings

  Rfunc["paste";("string1";"string2")]

  calling r substrate function

  Rfunc["substr";("text";1i;2i)]

  calling r max function for max value of a list of ints

  Rfunc["max";enlist "i"$til 5]

  defining a function with 2 params and calling

  Rcmd["my_function <- function(x,y) {(x+y)}"];
  Rfunc["my_function";2 5i]

What's Changed

• use r nanotime for timestamp. fixes loss of precision, null/inf mapping

q)Rset["a";2025.07.26D23:59:59.998999999]
q)"nanotime"~last Rget"class(a)"

• fix q datetime mapping to POSIXt and null/inf mapping
• fix q short null now maps to numeric null
• removed Rclose (prev performed no action)
• more tests & code clean-up
• moved q parsing into library c code
• fix table parsing
