In R 2.1.1, the default behaviour of scan() was changed to process all C-style escapes, even when a delimiter was specified using the 'sep' argument. A new argument 'allowEscapes' was introduced to turn this processing off. Because read.table() calls scan(), read.table() inherits the new default behaviour of scan() but without a way to turn it off. For example, reading a file testdata.txt' containing X A \0 C produces > read.delim("testdata.txt&quo...

...ng '\n' as newline. At least that's what I assume the problem is, but I can't identify which those might be or how to correct the problem. Below is my code and the problem output followed by sessionInfo(). This is executed in a loop, with i starting from zero. I also tried with 'allowEscapes = TRUE', but that made no difference. As you can see, the first FLAC file is followed by a '\n', which is ignored. This seems to happen about once in every 20 file names, so it does work properly most of the time. Also, when the file is opened in emacs, the newlines are recognized. c...

I'm trying to read in some data from a .csv format and have come across the following issue.

hi , I am reading a series of files by the command shown as below. cop_x_data<-read.table(flnm(i) ,skip=2,allowEscapes=TRUE,blank.lines.skip=TRUE) the first two line of the files are headfile and I skip them by skip=2. and sometimes the data file is null and there is no any data in the file except for the head information. At this situation,my command would be in the error and tell me that there is not data in t...

...r, in my example, initial testing with this command fails while the longer step of reading from a text file succeeds. Is there any reason for this? Is there any workaround for the problem with the textConnection command ? 2. There appear to be similiar problem with the read.table command. Using the allowEscapes =TRUE did not seem to help. Is there some other option here? Like, for example, temporarily setting another character like "<" as the escape character??

What is the inverse of encodeString? For example, \u1 is some Unicode symbol. If I do s <- encodeString("\u1") then s will be the string "\001". But anything I do with s, will not return the Unicode that corresponds to \u1: cat(s, "\n") # prints \001 cat("\u1", "\n") # prints y with umlaut Alberto Monteiro

Hi, I am trying to runn a age-period-cohort model, but here is what I am having problem with, hope you can help me! This is what I am trying to do: sumzero_a<-((A-min(A))/5+1) - mean((A-min(A))/5+1) where A is my age variable (numeric, the mid-point of a five-year age group), but I got the following error: Error in min(..., na.rm = na.rm) : invalid 'mode' of argument I am pretty
