Novice question about getting data into R
I found it easy to use R when typing data manually into it. Now I need to
read data from a file, and I get the following errors:
> refdata =
> read.table("K:\\MerchantData\\RiskModel\\refund_distribution.csv", header
> = TRUE)
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,
:
line 1 did not have 42 elements
> refdata =
> read.table("K:\\MerchantData\\RiskModel\\refund_distribution.csv")

Two last questions: about output
Here is my little scriptlet:
optdata =
read.csv("K:\\MerchantData\\RiskModel\\AutomatedRiskModel\\soptions.dat",
header = FALSE, na.strings="")
attach(optdata)
library(MASS)
setwd("K:\\MerchantData\\RiskModel\\AutomatedRiskModel")
for (i in 1:length(V4) ) {
x = read.csv(as.character(V4[[i]]), header = FALSE, na.strings="");...

Argh! Trouble using string data read from a file
Here is what I tried:
optdata =
read.csv("K:\\MerchantData\\RiskModel\\AutomatedRiskModel\\soptions.dat",
header = FALSE, na.strings="")
optdata
attach(optdata)
for (i in 1:length(V4) ) { x = read.csv(V4[[i]], header = FALSE,
na.strings="");x }
And here is the outcome (just a few of the 60 records successfully read):

Why isn't R recognising integers as numbers?
I have a number of files containing anywhere from a few dozen to a few
thousand integers, one per record.
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)

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. We don't yet have data spanning
