Here is a slight simplification of this one using row.names= in the read.table to avoid the subsequent manipulations. We use Lines0 defined in the earlier post:
# replace next line with something like Lines <- readLines("myfile.dat") Lines <- readLines(textConnection(Lines0)) Lines <- gsub("=", ",", Lines) Lines <- gsub(" ", "", Lines) DF <- read.table(textConnection(Lines), row.names = 1, sep = ",", fill = TRUE, colClasses = "character", header = FALSE) DF["CPU_SPEED", 2] On 9/27/06, Gabor Grothendieck <[EMAIL PROTECTED]> wrote: > Read in data using readLines and replace > = with comma and delete all spaces. > Then reread using read.table and set the > rownames to column 1 removing column 1. > > # test data > Lines0 <- "DEVICE = 'PC' > CPU_SPEED = '1999', '233' > " > > # if reading from a file then > # replace next line with something like Lines <- readLines("myfile.dat") > Lines <- readLines(textConnection(Lines0)) > Lines <- gsub("=", ",", Lines) > Lines <- gsub(" ", "", Lines) > DF <- read.table(textConnection(Lines), sep = ",", fill = TRUE, > colClasses = "character", header = FALSE) > rownames(DF) <- DF[,1] > DF <- DF[,-1] > > DF["CPU_SPEED", 2] > > > > > > On 9/27/06, Andre Jung <[EMAIL PROTECTED]> wrote: > > Hi, > > > > I would like to read values from an ASCII text file that contains > > information in the following format: > > > > DEVICE = 'PC' > > CPU_SPEED = '1999', '233' > > ... > > > > It's like a config file. > > > > How can I e.g. get R to read the 2nd value of CPU_SPEED? > > How do I go through text files and search for keywords and their values? > > > > Thanks a lot, > > Andre > > > > ______________________________________________ > > R-help@stat.math.ethz.ch mailing list > > https://stat.ethz.ch/mailman/listinfo/r-help > > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > > and provide commented, minimal, self-contained, reproducible code. > > > ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
