search for: constituents

I would like to reformat this data frame into something that I can produce some descriptive statistics. I have been playing around with the reshape package and maybe this is not the best way to proceed. I would like to use RiverMile and constituent as the grouping variables to get the summary statistics: 198a 198b mean mean sd sd ... ... etc. for all of these. I have tried

I've attached the .s file it produces in case you want to file a bug against grep.

I am writing a little abstraction for a series of tests. For example, I am running an anova and kruskal.test on a one-factor model. That isn't a particular problem, I have an interface like: my.function <- function(model,data) { print(deparse(substitute(data))) a <- anova(lm(formula,data)) print(a) if(a$"Pr(>F)"[1] < 0.05) { pairwise.t.test(???) }

I have read a large dataset into a dataframe using RODBC, the rows of data in the dataframe are (integer) timestamped and I would like to divide the original dataframe into n smaller dataframes where dataframe 1 contains all rows that had timestamps falling in the period 0-x1 minutes, dataframe 2 contains all rows that had timestamps falling between x1+1 and x2, etc.. Does anyone know how to

Dear friends: I'm interested to make a stacked plot of cumulative incidence. that's, the cuminc model is fitted [fit=cuminc(time, relapse)] and cumulative incidence is in place. I'd like to stack the cuminc plots (relapse of luekemia and death free from leukemia, for example) , then the constituent ratio of leukemia relapse and treatment related mortality is very clear. Can

...ifferent p-values, and which one is the most appropriate for my particular needs. First, let me describe the dataset I am working with. The project I am working on collected water samples from groups/networks of about 30 water wells and analyzed them for nitrate, major ions, and other chemical constituents. We revisited those same wells about 10 years later and analyzed the water samples for the same chemical constituents. I now have a paired dataset, and the question I would like to answer is whether there was a "significant" change in concentrations of those chemical constituents (suc...

QUESTION: is there a way to make objects (e.g. data frames) read-only? BACKGROUND: I am writing some functions that use a data frame (frequencies of tidal constituents) that I want to be read-only. I can see how to accomplish this within a single function (just define the data in the function), but I'm not sure how to share read-only values between (un-nested) functions. Is there a more elegant method than duplicating the creation of the data frame in each...

Hello users, I've noticed a problem when creating a stacked column plot when a column contains a negative and a positive value. e.g. series1<-c(-1,-2, 3, 4, 5) series2<-c( 5, -4,-3,-2, 1) data<-rbind(series1,series2) barplot(as.matrix(data), beside=FALSE) In these cases (i.e. first, third and fifth columns) the plotting is not handled correctly. Compare this output with that

Hi Hal, > Can anyone explain why LLVM can't do it? I've read vague hints of, "not > all the information is there," but I'd really like to understand this > better. The most compelling example I've heard is the x86_64 ABI. It refers to POD types, unions and structs with non-aligned fields. I think POD is a red herring because Clang would have to deal with that

We all know that LLVM codegen doesn't handle struct arguments...er...at all. Frontend code has to do a bunch of ABI lowering to make it work. Can anyone explain why LLVM can't do it? I've read vague hints of, "not all the information is there," but I'd really like to understand this better. Is there something we can do to make proper argument handling possible within
