rmysql

I am trying to query data from a mysql database, which contains some strings, of course. For the connection and data retrieval I am using RMySQL in R, which works fine. Apart from one thing: the strings I am retrieving seem not to be in utf8. But I need this, because I have some german "Umlaute" in these strings. When I ask teh databse, which are its encoding by dbGetQuery(db, "SHOW VARIABLES LIKE 'character_set_%';") I get the desired answer: Variable_name Value 1 character_set_client utf8 2 character_set_connection utf8 3 character_set_database utf8 4 character_set_filesystem binary 5

I am using DBI package to insert data to MySQL. Here is the code: ch <- DBI::dbConnect(MySQL()) dbSendQuery(ch, 'set character set "utf8"') dbSendQuery(ch, 'SET NAMES utf8') for (i in 1:nrow(test)) { query <- paste0("INSERT INTO trade_data VALUES('0', '", test[i, 1], "', '", test[i, 2], "', ", test[i, 3], "')") dbSendQuery(ch, query) } The problem is in 3td column, which is numeric, but have NA values. When loop comes to row which has NA value it returns an error: Error in .local(conn, statement, ...) : could not run statement: Unknown column 'NA' in 'field list' I tried to change NA to NaN,

I recently installed MySQL on my computer and am trying to connect RStudio to MySQL. I followed instructions in a book as well as instructions here . However, whenever I use dbConnect() or src_mysql in RStudio , I get this error message: Error in .local(drv, ...) : Failed to connect to database: Error: Plugin caching_sha2_password could not be loaded: The specified module could not be found For example, I might login to MySQL using the command prompt in Windows mysql -u username -p and create a database as follows CREATE DATABASE myDatabase; and then in RStudio: library(RMySQL) db <- dbConnect
