The statement "refdata18 = read.csv("K:\\MerchantData\\RiskModel\\Capture.Week.18.csv", header = TRUE,na.strings="")" works fine, and if I type refdata18, I get the integers displayed, one value per record (along with a record number). However, when I try " fitdistr(refdata18,"negative binomial")", or hist.scot...

Applying an R script to data within MySQL? How to?
...uot;merchants2") > rs <- dbSendQuery(con, "select * from merchants") > df <- fetch(rs, n = 150) > df And of course, that last statement is followed by the entire contents of "merchants" Now, I have a script like the following: refdata18 = read.csv("K:\\MerchantData\\RiskModel\\ndays18.csv", na.strings="") x1 = refdata18[,1] library(MASS) ex1 = fitdistr(x1,"exponential") str(ex1) Now, the contents of ndaysXX.csv represent records where one of the date values is in week XX of the current year.
