I realize it's -12C and we're having the next best thing to a blizzard but why can I not melt this data frame. I am missing something terribly obvious but I just don't understand what the error message is saying.

What am I missing? When I run the code below I get the error message "Error: ggplot2 doesn't know how to deal with data of class function" Googling suggests a message of "Error: ggplot2 doesn't know how to deal with data of class XXX" is not uncommon but I don't see why I am getting a "function" error unless I am using some reserved word?

Dear all, I need some help on plotting multiple boxplots on one figure. I have three matrix A, B and C. Each of them is a 1000 by 10 matrix. The 10 columns of all three matrix correspond to the 10 values of the same parameter, say k=1, ..., 10. I want to make a plot where x axis represents different values of k. For each k value, I want to plot three boxplots, one on top of another. For

I am getting what appears to be an Unbuntu level error in trying to install the XML package. Both commands: install.packages("XML:) install.packages("XML", dependencies = TRUE) give an error . The full installation script is below but the problem to my very inexperenced eye seems to be here: checking for pkg-config... /usr/bin/pkg-config checking for xml2-config... no Cannot

Dear all, I want to get a series of boxplots (grouped by two factors) and I want to overlay the original observations and the following code does almost what I want: library(ggplot) ddf <- data.frame(x=factor(rep(LETTERS[1:4], each=30)), y = runif(120,0,10), grp = factor(rep(rep(1:3, 10), 4))) ggplot(ddf, aes(x, y, colour=grp)) + geom_boxplot() + geom_point() Yet the position of the points

It looks like an encoding problem. It works fine for me with R encoding set to UTF-8 Here is part of my sessionInfo() results [1] LC_CTYPE=en_CA.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_CA.UTF-8 LC_COLLATE=en_CA.UTF-8 [5] LC_MONETARY=en_CA.UTF-8 LC_MESSAGES=en_CA.UTF-8 I would suggest issuing the command sessionInfo() and seeing what your encoding is.

Dear All, I have a data sets as shown below A (Patient ID ), B and C are the Concentration of drug in blood on day 1 and day 4, D is the difference in conc. To do this in R I have written a code as follows, identified the number of patients who have more concentration on day 4 . Here I want to identify specifically the patient ID (is he patient 1 or 2 or 5 and 7), whose concentration is more. How

Dear mailing list members, I am a beginner of this community. I would like to analyze data in a .rdata file. I ran the following code, but the object "d" remained empty. d <- load("~/docdis/input/ch2/WV6_Data_R_v_2016_01_01.rdata") I would like to know how to convert this file format into .csv or .txt. I suppose this question is very basic, but I could not find solutions

Thank you so much Rui. 1. How do I export this table to excel file? I used this tbl1 <- table(Country, IDNum) tbl2=addmargins(tbl1) write.xlsx(tbl2,"tt1.xlsx"),sheetName="summary", row.names=FALSE) The above did not give me that table. 2. I want select those unique Ids that do have records in all countries. From the above data set, this ID

Welcome to the forum .Rdata may contain many different objects. I would suggest doing a? "ls()" to see what objects you have. then have a look at ?write.table or ?write.csvThese commands will write many types of objects to a .csv file. For example if I have a data.frame called "dat1" I can write it to a csv (text) file like this: write.csv(dat1, "~/Rjunk/mydata.csv")

Hello all, I have files (see attached) which are created daily. I want to load about a weeks worth of them (7 daily files) and plot a weeks worth of one variable together. So one variable name is delta_D_H. I would like to plot this variable from all 7 days on one plot. I'm having trouble figure out how to do this. I've loaded them all up using this time=Sys.time() t1<-

Hi All, whenever I open R using the shortcut on desktop, there are 2 active datasets in the workspace, I tried to start the program from Start menu, same thing!!

I am lousy at simple regex and I have not found a solution to a simple problem. I have a vector with some character values that I want to split. Sample data dd1 <- c( "XXY (mat harry)","XXY (jim bob)", "CAMP (joe blow)", "ALP (max jack)") Desired result dd2 <- data.frame( xx = c("XXY", "XXY", "CAMP",

Hello everyone I have some data of the following type. 100 200 300 400 500 1.1 1.2 1.3 1.4 1.5 600 700 800 900 1000 1.5 1.7 1.9 2.0 2.4 With plot() and points functions I can plot these 4 lines of data. But I dont know how to do it with qplot or ggplot functions. The scenario is something like this: the hundreds should appear on x-axis and the fractional values of y axis. Thanks alot. MEMON

Dear all, I am a R beginner, and I am looking for a way to do the same thing for all levels of a column in a table. Basically, I have a bunch of protein sequences composed of different amino acid residues, and each residue is represented by an uppercase letter. I want to calculate the ratio of different amino acid residues at each position of the proteins. Here is an example table: Proteins

Dear all, I'm looking for primary help at aggregating table() results and at writing a loop (if useful) My dataset ( http://goo.gl/gEPKW ) is composed of 23k rows, each one representing a point in the space of which we know the land cover over 10 years (column y01 to y10). I need to analyse it with a temporal sliding window of 5 years (y01 to y05, y02 to y06 and so forth) For each period

I am completely misunderstanding how to handle dates. I want to plot a couple of data series against some dates. Simple example 1 below works fine. Unfortunately I have multiple observations per day (no time breakdowns) and observations across years. (example 2 very simplistic version ) Can anyone suggest a quick fix or point me to something to read? I thought that zoo might do it but I seem
