Hello, When I am writing in sqldf or RSQLite I lose the decimals in my matrix. The only way I can get decimals is by multiplying by 1.00000, etc. I have tried manipulating the options, but it is only effective once I multiply by 1.0000. I appreciate any suggestions! Thanks! Example: z <- sqldf ("select ST, SUM(AGEP*PWGTP)*1.000000000/SUM(PWGTP)*1.00000000000000 as wgtage from ss09

Hi, I am trying to aggregate the sum of my test data.frame as follow: testDF <- data.frame(v1 = c("a", "a", "a", "a", "a", "b", "b", "b", "b", "b", "c", "c", "c", "c", "c", "d", "d", "d", "d",

Hello R folks, Reproducible code below - I'm trying to do a weighted mean by a factor and can't figure it out. Thanks in advance for your assistance. Mike data<-data.frame(c(5,5,1,1,1), c(10,8,9,5,3), c("A","A","A","B","B"))

Hello, I'm having trouble discovering what's going wrong with my use of natural joins via sqldf. Following the instructions under 4i at http://code.google.com/p/sqldf/, which discusses creating indices to speed joins, I have been only unreliably able to get natural joins to work. For example, > Tid <- c('AES 01-01-02 10:58:00', 'AES 01-01-02 11:53:00', 'AES

We've only switched from redhat 7.3 to 9 several weeks ago, and I found today, that the last three pages of demo(plotmath) uses quite wrong plot symbols, e.g sum(....) gives (+) {+ in circle} instead of the Sigma-like summation --- but only in "text" not in title, i.e., probably a font problem. With postscript() {and hence dev.print() of x11()} all is fine. Hence it must be an X

I've been using sqldf heavily lately but have encountered problems with ordering of observations or calculating statistics such as max() and min() when the variable used is of class Date. For example, if I run the following code: =============== begin code ================= library(sqldf)

Hi, sqldf is a fantastic package, but when the SELECT procedure runs unused levels remain in the output. I tried with the drop function, but without success. Do you have any suggestions? Thanx, Gianandrea data(iris) require(sqldf) base<-sqldf("select * from iris where Species <> 'setosa'") str(base) # Species with 3 levels! -- View this message in context:

Hello Group, I am having trouble with the sqldf package on unix. The same code works fine on windows.

sqldf is an R package for running SQL select statements on one or more R data frames. It is optimized for convenience making it useful for ad hoc queries against R data frames. Given an SQL select statement whose tables are the names of R data frames it: - sets up the database (by default it transparently sets up an in memory SQLite database using RSQLite; however, MySQL via RMySQL, can be

Dear all, I recently read the book " R data preperation and manipulation using sqldf package" by Djoni Darmawikarta However, I have a problem with manipulation of dates using this package, I do not get the expected results. Do I need to install some packages to be able to subset the data by dates in sqldf? I am not getting Djoni Darmawikarta email address. Please see the practice

I am trying to exclude integer values from a small data frame 1, d1 that have matching hits in data frame 2, d2 (Very big) which involves matching those hits first. I am trying to use sqldf on the df's in the following fashion: df1: V1 12675 14753 16222 18765 df2: head(df2) V1 V2 13647 rd1500 14753 rd1580 15987 rd1590 16222 rd2020.....

Hi, I am running a query using sqldf() [package : sqldf]. The query is:- userid <- 5 taskid <- 5 tab1 <- fn$sqldf("SELECT tobiiEvents.data1, tobiiEvents.data2, events.`timestamp` as tobiiTime FROM tobiiEvents INNER JOIN events ON events.eventid = tobiiEvents.eventid WHERE tobiiEvents.subtype = 'MOUSE' AND tobiiEvents.userid = 5 AND tobiiEvents.taskid = 5 ORDER BY

This is my first post. I am running Mac OS X version 10.6.3. I am running R 2.11.0 GUI 1.33 64 bit. This may or may not be related to sqldf, but I experienced this problem while attempting to use an sqldf query. The same code runs with no problem on my Windows machine. Here is what happens: > r=sqldf("select ... ") Loading required package: tcltk Loading Tcl/Tk interface ... Then

Hey guys, So I'm working with a project where I manage a database within R, and I'm developing a script/function that will automatically run my queries in R depending on the date parameters passed in. The problem is that when I create variables for the dates, and use those variables in my sqldf statements, R says that there is no such column in the dataframe (which is true!). My question

Hi everyone, I have the following: sqldf("select Premie,count(tpounds) N,avg(tpounds) Avg_Weight, stddev_samp(tpounds) StdDev from children group by Premie having !is.na(Premie)") sqldf() does not like the !is.na(Premie) specification. How does one exclude a "missing" group in an aggregated query using sqldf()? Thanks! Dan [[alternative HTML version deleted]]

Hi, I am new to R and trying to migrate from SAS. I am trying to use sqldf to create a new table from existed table and change some of the columns.
