Dear Colleagues, I have a data set that looks as below. I'd like to count the number of dates in a series of arbitrary ranges (breaks) i.e. not pre-defined breaks such as months, quarters or years. table(format()) produces ideally formatted output, but table() does not appear to accept arbitrary ranges. I also tried converting the dates to numeric and using histogram to try to get the data,

Hello, I'm trying to read in 50 text filess with dates as content to create a list of tables. a is the list of filenames that need to be read in. The following command returns the following error mylist<-lapply(a, read.table(header=TRUE, sep="\n")) Error in read.table(header = TRUE, sep = "\n") : element 1 is empty; the part of the args list of

Dear colleagues, I have a dataset that looks as below. I would like to make a new dataset that excludes the cases which are joint conjunctions of particular state names and years, so Connecticut and 2010, Maryland and 2010 and Vermont and 2010. I'm trying the following subset code: newdata<- subset(bpa, (!State=="Connecticut" & year<"2010")) It appears that

Hello all, I'm having difficulty getting one particular variable into R from SPSS v. 16.0 for mac. R version is 2.10.1. I saved the relevant variables from SPSS into a .csv file and then read them into R. All the variables worked fine, except for one (enviro_spending). In the SPSS file it is correctly coded as a nominal variable and there is nothing that I can tell that

Dear colleagues, I have the following dataset. It is modelled on the data included in Box-Seteffenheiser and Jones "Event History Modelling" Using the following code, I try to find the baseline hazard function haz_1<-muhaz(bpa$time, bpa$censored, subset=(bpa$year=="2010" | bpa$ban=="1"), min.time=1, max.time=3) I think I'm doing everything right, but what I

Dear colleagues I'm using data that looks like .test and .test1 below to draw two mosaic plots with cell labelling (the row percentages from the tables). When I take out the pop=FALSE commands in the mosaic commands and comment out the two lines labelling the cells, then the plots are laid out exactly as I'd like: side-by-side. But I do require the cell labelling and the pop=FALSE

Dear colleagues, i found a line or two of code in the help archives from Uwe Ligges about creating slanted x-labels for a barplot and it works well for my purposes (code below). However, I was hoping someone could explain to me precisely what the code is doing. I'm aware it's invoking the text command, and I know the first ttwo arguments to text are x and y co-ordinates. I'm also
