Hello, I'm attempting to write a code that automatically imports data from different files (with different lengths-just one variable) and makes tidy box plots for comparison. I can successfully import the data and create a list of the vectors I want to compare. But I cannot, for the life of me, figure out how to generate box plots using the "list" option. Suppose these are my data:

Hi all, I'm trying to identify a particular digit or value within a vector of factors. Specifically, this is environmental data where in some cases the minimum value reported is "<" a particular number (and I want to manipulate only these). For example: x<-c("1","2","3","4","<1") For a dataset that is hundreds or

Hi all, I have two datasets, one that represents a long-term time series and one that represents summary data for the time series. It looks something like this: x<-data.frame(Year=c(2001,2001,2001,2001,2001,2001,2002,2002,2002,2002,2002,2002), Month=c(1,1,1,2,2,2),Q=c(5,5,5,6,6,6,3,3,3,4,4,5)) y<-data.frame(Year=c(2001,2001,2002,2002),Month=c(1,2,1,2),Threshold_Q=c(5,5,4,4)) What I'd

Hi all, I'm attempting to make a quite-specific plot where the axes cross at the origin and with gridlines for guidance. I've been using ablines to create the reference lines because I want a lot of control as to where they are placed on the axis. This command works very well for such control. However... These ablines don't seem to work when I specify the origin as 0,0. They go

Hi all, I'm relatively new to R and have a data management problem. I am importing a data matrix with some columns that have missing values. I am trying to figure out how to delete rows with NA for data FOR JUST ONE SPECIFIED column. For instance, with the example matrix: x<-matrix(nrow=5,ncol=3) x[,]<-1 x[5,1]<-NA x[3,3]<-NA how do I tell R to delete any rows with an NA value

Suppose I have a Master.Rnw file that looks something like this: \documentclass[12pt]{mypaper} \usepackage[margin=1in]{geometry} \usepackage{setspace} \usepackage{url} \usepackage{indentfirst} \usepackage{fancyhdr} \usepackage{Sweave} \pagestyle{fancy} \lhead{sonographic rectal diameter and ADHD} \rhead{ } \usepackage{abbrevs} %\usepackage{natbib} %\usepackage{apacite}

Hi all, I'm trying to import Microsoft Access data into R. It looks like I'm supposed to use the ROBC package, and this works fine with old Access files (those with an .mdb extension). However, lovely Microsoft must constantly update their software. Modern Access files have an .ACCDB extension. I cannot seem to coerce R to import data from such a file. Any advice? I've been using

I ran 2 tests. One using proto''s Event.observe, and another using an in-line handler of the "keydown" event in a textbox. Using .bindAsEventListener, the event.keyCode is always returning a capital letter, no matter what. The in-line event handler returns lowercase vs. uppercase correctly... What''s going on? I guess I find it hard to believe no one has tried

Hi all, I am very new to R and I'm trying to import data from Microsoft Access. So far, I've managed to do so successfully using the following code: testdb <- file.path("c:\Databse.accdb") channel2 <- odbcConnectAccess2007(testdb) data.table <- sqlFetch(channel2,"data") This successfully imports a table(?) called "data.table". But when I try to

I am trying to find out why my group names are showing as nobody. I have a CentOS 6 system that is acting as a NFS server. I have some older fedora clients where the group name shows up fine, but newer CentOS 6 clients have the group name for NFS mounts show up as "nobody". The username shows up fine but the group name shows up as "nobody". I have tried changing some setting

Hello, I have a very large content analysis project, which I've just begun to collect training data on. I have three coders, who are entering data on up to 95 measurements. Traditionally, I've used Excel to check coder agreement (e.g., percentage agreement), by lining up each coder's measurements side-by-side, creating a new column with the results using if statements. That is, if

Hi, I have a data matrix in which there are 1000 rows by 30 columns. The first column of each row is a numeric indicating the number of trips taken to a particular location with location attributes in the following column entries for that row. I want to repeat each row based on the number of trips taken (as indicated by the number in the first column)...i.e., if 1,1 indicates 4 trips, I want

Hi! I've performed a Google Scholar Search using a query, let's say "Frank Harrell", and parsed the links to the EndNote references from the resulting HTML code. Now I'd like to download all the references automatically. For this, I have tried to use RCurl, but I can't seem to get it working: I always get error code "403 Forbidden" from the web server.
