r - Writing to specific schemas with RPostgreSQL

Question

I'm using RPostgreSQL to read and write data. Reading from any schema works perfectly, but I'm not able to write to non-public schemas. For example, the following code places a table in the public schema, with the name myschema.tablex

# write dataframe to postgres 
drv <- dbDriver("PostgreSQL")
con <- dbConnect(drv, host="localhost", user="postgres", password="zzzz", dbname="mydatabase", port="5436")
if(dbExistsTable(con,"myschema.tablex")) {
  dbRemoveTable(con,"myschema.vkt_tablex")}
dbWriteTable(con,"myschema.tablex", dataframe, row.names=F)

What I want to do, is to place the table tablex in the schema myschema. I've also tried to name the schema in the connection: dbname="mydatabase.myschema" and trying the argument schemaname which I saw referred to in an earlier bug.

None of these approaches work, so I'm wondering if there is another method that I can use.

Use this:

library(RPostgreSQL)
drv <- dbDriver("PostgreSQL")
con <- dbConnect(drv, dbname = "db", host = "host", port = 5432,
                 user = "user", password = "pwd")
dbWriteTable(con, c("yourschema", "yourtable"), value = yourRdataframe)
dbDisconnect(con)
