similar to: Printing data as a narrative or form letter rather than as a table

When one has raw data it is easy to create a table of one variable against another and then calculate proportions For example a.nice.table<-table(a,b) prop.table(a.nice.table,1) However, I looked at several papers and created a data frame of the aggregate data. That means I acually created a table except it is a data frame. The first column lists the name of the first author and the year. I

Is there an easy way to read the value of the cells rather than the formula?So for instance in a cell whose value was created by simply using the value from the cell immediately to the left in the Google spreadsheet I would prefer to get the value rather than =RC[-1] When one exports with Google Spreadsheets as a csv then that does not happen. I am using the following line of code in R

Hi, I'm new to R and would like to know, how one can populate the list with array data. I'm reading a tab separated table in R. The data in the table looks something like this. #Table Data Comp    A    B    C Extracellular    103    268    535759 Nucleus    45603    47783    442744 #R code myData <- read.table("table.data",                 header=T,                

converting a POSIX class variable to a date class is easy. dates<-as.Date(x) #where X is of class POSIX How does one do that to all columns in a data frame that are of POSIX class and leave all the other columns (integers, factors) as is. Feel free to reply with just one or two buzzwords that I could then search for to find how to do it. Farrel Buchinsky

This ought to work: resultdt <- lapply(PGWide[, 240:389], function(x, ...) try(tdt(x, ...))) You can then check the class of each component to see which one failed.

I want R to read my Microsoft Access database or maybe even a Sybase database. I installed RODBC or at least thought I did. Then I issued the following command: library(RODBC) And got Error in lazyLoadDBfetch(key, datafile, compressed, envhook) : ReadItem: unknown type 241 In addition: Warning message: package 'RODBC' was built under R version 2.3.0 Error: package/namespace

I would really appreciate it if anyone could determine what is going on with the following command. It is only half-working and is losing lots of data. For the life of me I cannot even see the pattern of what it is losing and what it is not. I am attaching the R data set which you can use with the Load Workspace menu function.

I suspect the problem stems from the fact that there are a couple of NA values. > sunflowerplot(lastoto,maxear) Error in rep.int(i.multi, number[number > 1]) : invalid number of copies in rep.int() So I used the subset command to get rid of the cases with NA hell<-subset(ChinOtoMayB,is.na(lastoto)==FALSE) Then it worked perfectly sunflowerplot(hell$lastoto,hell$maxear) Is

I have upgraded everything lately and can no longer get the Tinn-R explorer to work. I think I have had this problem before but cannot recall how I solved it.I run Tinn-R 2.0.0.7 and Rgui version 2.7.2 When I click on the explorer button I get > trObjList(envir='.GlobalEnv', pattern='', group='', path=.trPaths[3]) Error in trObjList(envir = ".GlobalEnv",

I read a table from Microsoft Access using RODBC. Some of the variables had a name with a space in it. R has no problem with it but I do. I cannot find out how to specify the space names(alltime) [1] "ID" "LVL7" "Ref Pv No" "Ref Pv Name" "DOS" "Pt Last Name" "Pt First Name" "MRN"

I have a bunch of tables in a Microsoft Access database. An updated database is sent to me every week containing a new table. I know that is inefficient and weird but welcome to my life. I want to read the tables whose names are something such as "040207" but not the ones that have alphanumeric names such as "everyone". Using RODBC I am easily able to create a character vector

Why will the following command not work sapply(objects(),dim) What does it say about the objects list? What does it say about the dim command? Likewise, the following also does not work all<-ls() for (f in all) print(dim(f)) -- Farrel Buchinsky [[alternative HTML version deleted]]

I saw a thread from September 24 in which Duncan Temple Lang told us: - The package currently has no Rd files, but there is a brief "user's guide". The package is available from http://www.omegahat.org/RGoogleDocs I could not find it by using Tinn-R or RGui's package install tool. Then when I went to the website I saw that package is only available as

The author of the package, Duncan Temple Lang posted an update. I have installed it and now can list my spreadsheets but alas I cannot read the data within any of them. Has anybody been able to get it to work. I would love to see a real live example of sheetAsMatrix I am not sure how to specify sheet and con = sheet@connection. I have tried many ways but just get: Error in !includeEmpty : invalid

I installed the newest version of R and once again ran into problem with Tinn-R failing when trying to use the R explorer. I had this problem once before and solved it when I added the following .trPaths = c( 'C:/Documents and Settings/fbuchins/Application Data/Tinn-R/tmp/', 'C:/Documents and Settings/fbuchins/Application Data/Tinn-R/tmp/search.txt', 'C:/Documents and

Power calculations two sample test for proportions is very useful. Is there a way however, to get away from the two samples being of the same size. What would happen if one had n=15 in the one sample and n=45 in the other sample.

I have a vector containg about 20 unique values. It is called rejectrs$rs. It is a factor I have a data frame with about 100000 rows. I want to exclude all rows where in variable rs the value is one of the 20 on the exclude list. I thought this would work but none did. RawSeqBig<-subset(RawSeqBig,ASSAY_ID!=rejectrs$rs) RawSeqBig<-subset(RawSeqBig,ASSAY_ID!=list(rejectrs$rs)) -- Farrel

I have solved this problem once before but don't recall exactly how. Is there a url that shows how? What I want to do now is quite specific but my query is actually very general There are many functions in which one specifies several parameters and an output is generated. Well what happens if one wants to specify a range of parameters and have the output written to a data frame. To

All, I would like to apply a set of rules to each row of the sample data set below. The rule sets are the guidelines for determining an individual's date for retirement eligibility. The rules are found in this document, http://www.opm.gov/feddata/RetirementPaperFinal_v4.pdf. I am only interested in the top two categories for retirement eligibility, the CSRS and FERS plans. The data set has

I am aware of the R Genetics Project that developed the R library and software called Bioconductor (http://www.bioconductor.org/ ) . How do the two relate to each other? What is the one that the other is not and vice versa? Can anybody link me to something that answers the question? -- Farrel Buchinsky, MD Pediatric Otolaryngologist Allegheny General Hospital Pittsburgh, PA
