View(df) in R throw (function(x, df1, df2, ncp, log = FALSE))

I connected R with SQL Server (in Visual Studio 2017) the connection succeeded this is Setting.R settings <- as.environment(list()) dbConnection1 <- 'Driver={SQL Server};Server= (local);Database=SaVeITDB;Trusted_Connection=yes' this is SqlQuery.sql also executing the below query succeeded -- Place SQL query retrieving data for the R stored procedure here select AOIName from AreaOFInterest a, ProjectsAOI p where p.AOIId = a.AOIId; and this is Script.R when I executing it throw this function in df file source("Settings.R") library(RODBC) conn <- odbcDriverConnect(connection = dbConnection) df <- sqlQuery(conn, iconv(paste(readLines('c:/users/comnet/source/repos/rproject3/rproject3/sqlquery.sql', encoding = 'UTF-8', warn = FALSE), collapse = '\n'), from = 'UTF-8', to = 'ASCII', sub = '')) View(df) this df file (appears with lock icon) function(x, df1, df2, ncp, log = FALSE) { if (missing(ncp)) .Call(C_df, x, df1, df2, log) else .Call(C_dnf, x, df1, df2, ncp, log)} **Edit** It's executing correctly without any error after run Visual studio as admin
