I am trying to delete a section of rows from a data frame (based on no condition). Lets say my data frame has 200 rows and I want to delete rows 1 through 25. How would I do this? I know x[ -1, ] deletes the first row (or any desired row). I tried using different variations of this, like x[ -c(1:25), ] but that didn't work. I also tried writting a few functions, for example: deleteRows

I'm trying to calculate the percent change for a time-series variable. Basically the first several observations often look like this, x <- c(100, 0, 0, 150, 130, 0, 0, 200, 0) and then later in the life of the variable they're are generally no more 0's. So when I try to calculate the percent change from one observation to the next, I end up with a lot of NA/Nan/INF, and

I have an external data (.txt) for annual peak flood. The first column is the year, second column is the observation date, and the last is the observed discharge. My task is to calculate the mean, skewness and kurtosis of the said data. I was advised to use read.table() to read the entire data. Please help me on how to perform the required computation. I am obviously a new user of this statistical

The prob package has been archived because it depends upon some other packages which have issues. However, such projects as Introduction to Probability and Statistics in R depend upon it for learning. There are a few other resources that also use it. Does anyone know of any workarounds? Someone at stack exchange mentioned using R 2.9. However, that broke my RStudio (WSOD) and the dependent

Hello I do not know very much about statistics (and English language too :-( ), then I come in search of a clarification (explanation): I found two distinct results on KURTOSIS and I do not know which of them is the correct one. Any aid will be welcome! klebyn ################ CODE rnorm(1000) -> x library(moments) kurtosis(x) skewness(x) detach("package:moments")

Hello R-Users, The following questions are not R-technical, but more of general statistical nature. 1. NORMALITY I built a normal linear regression model and now I want to check for the residual normality assumption. If I check the distribution graphically and look at the descriptive characteristics (skewness and kurtosis are below 1), I would confirm that the residuals are normally

Dear R helpers If for a given data, I need to calculate Mean, Standard Deviation, Mode, Median, Skewness, Kurtosis, is there any package in R, which will calculate these moments? Individually I can calculate these, but if there is any function which will calculate these at a stretch, please let me know. Maithili The INTERNET now has a personality. YOURS! See your Yahoo!

The issue is fAsianOptions. Is there a version that works with the latest version of R? If not, which version of it works with which version of R and where can it be found? I tried several at the archive already. Alternatively, is there another package that behaves similarly to prob?

Yes. That's the version I've been discussing that has non-zero exit status. That situation is why CRAN retired the prob package. It's possible you installed that library earlier in development and it's been "carried" along. It no longer installs, now. The problems with all of this seem to have started this month according to the conversations. However, no one has

Hi, Does anyone know if the D'agostino test is available with R ? Alex

Yes, that is exactly what I was doing two days ago. Warning in install.packages : installation of package ?fAsianOptions_3010.79.tar.gz? had non-zero exit status Which is what a reading of the explanation for why "prob" was retired leads one to expect. Do you have some other suggestion about how to get it to work? I notice you're not using Windows which might have a relationship

Rtools is not available for the current version of R. What I'm looking for is an alternative package or how others have managed to create workarounds.

Thanks. I found that, and installed it and got the same message.

Hi all, I'm wondering if there is a function that can return summary statistics: N=total number of observation, # missing, mean, median, range, standard deviation. As I know, summary() returns some of info I've mentioned above. Thanks, SY [[alternative HTML version deleted]]
