Hi all, I would like to run the following from within R: awk '{$3=$4="";gsub(" ","");print}' myfile > outfile However, this obviously won't work: system("awk '{$3=$4="";gsub(" ","");print}' myfile > outfile") and this won't either: system("awk '{$3=$4='';gsub('

Hi all, I am trying to download, decompress and read a csv file. My code: myurl <- "ftp://ftp.ncbi.nih.gov/pub/geo/DATA/supplementary/series/GSE24729/GSE24729_MitoNuclear_suppl_male_stats.csv.gz" # myfile <- "GSE24729_MitoNuclear_suppl_male_stats.csv.gz" # download.file(myurl, destfile=myfile, mode="w") # mycon <- gzcon(gzfile(myfile,

Dear R-users, My script imports a dataset from a csv file, in which missing values are represented by ".". This importation is done into a dataframe using the read.table function with na.strings = "." Then I want to replace the NAs in the first column of the dataframe by "Missing data". I am using the following code to do so :

I have a file in stata format, which I have read in, and I am trying to create a text file. I have exported the data using various delimiters, but I'm unable to read it back in. I originally read in the file with: library(foreign) myData <- read.dta("mydata.dta") I then exported it with write.table using comma, tab, and exclamation marks as a delimiter. When I was unable to

I have a time series with many millions of points. Each point is of the form (time, value) but where the value is 0 there is no record - ie the data set is sparse. If I plot this using plot(myData) I get a correct plot going from time 0 to time 7x10e7. Given that there are many millions of points (it's not *that* sparse), this looks very busy. But if I attempt to plot this as a line -

Dear All, I want to save the XML representation of a model using PMML. Then I want to read the model and predict using the model and a new dataset. This is described in this blog post : https://www.r-bloggers.com/predictive-modeling-using-r-and-the-openscoring-engine-a-pmml-approach/ I am able to save the PMML representation of the model. I am not able to read this representation convert it

Hi, i am trying to read a .txt file, do a couple of select if statements on my data, and then finally use the ?table function to get frequency counts on the data. Specifically, i am looking at answering the following question: What is the frequency of Grade 7 students in the province of Alberta who are smokers? I am having some problems: 1)i cannot get the column names to show up when print

Dear all, In R<=1.6.2 I usually used the following code (in DOS prompt) to run R in batch mode C:\documents> Rcmd BATCH myfile.R and I could see the results (including warning messages) in the file myfile.Rout In R.1.7.0 I'm experiencing the followings: (1) even if I type "Rcmd BATCH myfile.R myfile.Rout", no file myfile.Rout is created, but just a "&1" file

Hi Guys, I have already tried this one on the developers list. I have not been successful getting much back there and I have notified them that I will post this on the users list instead. Hopefully somebody have tried something similar and can help out. I am developing AGI scripts on Asterisk and have run into some very strange behaviour and I think this is a bug, but I am not completely sure.

RE: Compression Hi R-Users, You can deal with pretty decent size data sets in R on a relatively new computer. I have one that I have been working with that is a nearly 100MB plain text file. With storage as inexpensive as it is these days that's not really all that much data and I could store it just as it is. Having said that you may want to compress those data files. There are two

Hello, I read in a tab delimited text file via mydata = read.delim(myfile). The text file was originally an excel file where . was used in place of 0. Now all the columns which should be integers are factors. Any ideas how to change all the . to 0 and factors back to integer? Thanks a lot in advance for any suggestions, -- D --------------------------------- [[alternative HTML

Hi there, I am trying to export a regression output to Latex. I am using the xtable function in the xtable library. Doing myfit <- lm(myformula, mydata) print.xtable(xtable(myfit), file="myfile") only returns the estimated coefficients and the correspondent standard erros, t-statiscs and p-values. But I wish to get a bit more, say, the number of observations used in the

I am trying to find the important factors from a two level fraction factorial design (2^{8-4}) I have studied the companion of vikneswaran but would really like a basic example of how to do this: (adapted to 8 factors): mydata<-read.table("myfile.txt", header=T) summary(aov(resp ~ A*B*C*D*E*F*G*H, data = mydata)) However i can't figure out how the input files are supposed to

Hello r-help, I am using the excellent np package to conduct a nonparametric kernel regression and am having some trouble plotting the results. I have 2 covariates, x1 and x2, and a continuous outcome variable y. I am conducting a nonparametric regression of y on x1 and x2. The one somewhat unusual feature of these data is that, to be included in the dataset, x1 must be at least as large as x2.

hello, I got a problem with plotting large time series, since I want to store the results in a .PDF file (I want to store several pages of plots). The PDF files get too large to be handled (> 10MB, one was even 200MB big). So I wonder, if there would be a possibilty to either - reduce the file size of the PDF - change the way the plot is generated to reduce the plot size? I use:

Hi, I have used the mgcv library to generate a simple additive model. I want to know how to plot the function on the raw data with confidence intervals whan I have TWO variables in the model. I get it to work with one variable but not with two. I am on the limit for what I understand in R, so be gentle. I have read the help file on predict.gam, but did not get any help out of it. #My model:

I am using density() to plot a density curves. However, one of my variables is truncated at zero, but has most of its density around zero. I would like to know how to plot this with the density function. The problem is that if I do this the regular way density(), values near zero automatically get a very low value because there are no observed values below zero. Furthermore there is some density

There was a discussion on r-help of getting the output from print.packageInfo into a file. Spencer and I have added a file= argument to print.packageInfo for consideration in R. Had this been available it would have simplified the answer to that thread. If the file= argument is used then the packageInfo information is sent to the file specified rather than displayed using file.show .
