Dear group, Is there a way I could avoid the sort of duplication illustrated below? i.e., I have the same dplyr::summarise function on different group_by arguments. So I'd like to create a single summarise function that could be applied to both. My attempt below fails. df <- data.frame(matrix(rnorm(40), 10, 4), f1 = gl(3, 10, labels = letters[1:3]), f2 = gl(3, 10, labels = lett...

Hi,I am using the amazing package 'plyr". I have one problem. I would appreciate help to fix the following error: Thanks. ______________________________ > library(plyr) > data(baseball) > summarise(baseball, + duration = max(year) - min(year), + nteams = length(unique(team))) Error: could not find function "summarise" > ddply(baseball, "id", summarise, + duration = max(year) - min(year), + nteams = length(unique(team))) Error in llply(.data = .data, .fun = .fun, ..., .p...

Hi Lars, Two comments: 1. You can achieve what you want with a slight modification of your definition of s(), using the hint from the error message that you need an argument '.': s <- function(.) { dplyr::summarise(., x1m = mean(X1), x2m = mean(X2), x3m = mean(X3), x4m = mean(X4)) } 2. You have not given a great test case in how you set your two factors because the two group_by()'s will give the identical groupings, An alternative which confirms th...

I have some summarised data from a 2D pivot table which I want to visualise in R. How can I read in the data as a R table so I can use mosaicplot()?

I am currently summarising a data set by collapsing data based on common identifiers in a column. I am using the 'aggregate' function to summarise numeric columns, i.e. "aggregate(dat[,3], list(dat$gene), mean)". I also wish to summarise text columns e.g. by concatenating values in a comma separated list, but the aggregate function can only return scalar values and so something like "aggregate(dat[,3], list(dat$gene), cat)&quo...

Dear list, For a reason it would take me long to explain, I need to do something along the lines of what's shown below -- i.e., create an object from dplyr::summarise, and then evaluate it on a data frame. I know I could directly do: df %>% dplyr::summarise(x1_mean = mean(x1)) but this is not what I'm looking for. library(dplyr) df <- data.frame(x1 = rnorm(100), x2 = rnorm(100)) foo <- function(df) { mySummary <- quote(dplyr::summarise...

...) Fi = percentual frequency of occurrence of a food item Vi = percentual volume of a food item So, using ddply (plyr) function, I was able to calculate the total frequency of occurrence and total volume of each food item, using: Frequency = ddply (dieta, c('Specie','Fooditem') , summarise, Frequency = sum (Occurrence)) Volume = ddply (dieta, c('Specie','Fooditem') , summarise, Volume = sum (Volume)) and calculate total frequency and total volume for a given specie: TFrequency = ddply (Frequency, 'Specie' , summarise, TF = sum (Frequency)) TVolume = ddply...

...oduced several models, named model1, model2, model3, etc... I would like to extract several elements from each model's object, e.g. at minimum the estimates, SEs, and P values of each model's intercept and slopes, model R-squared, and AIC... ...and then produce a new object (a table) that summarises all of my models, with M\models in rows and extractd model elements in columns. Before reinventing the wheel, I wonder if there is a package or function that does what I need? Thank you! Mark Na [[alternative HTML version deleted]]

Hi all - I'm on R 2.5.1 for XP. in the systemfit package, the summary is set to print the McElroy's measure of fit unless it's NULL. When the option saveMemory = TRUE, the McElroy isn't included, instead it defaults to NA. Thus I am unable to use summary.systemfit. > library(systemfit) > example(systemfit) > surfit2 <-

Hello 1* I need to use logistic regression. But my data file is very huge( appx. 4 million line). R doesn't handle such a file. What can I do ? ------------------------ 2* So, I thought whether I could perform sta. analyses on summarised data (count of yes/no values) of the huge file. Normally, summarised data file short and R could handle it. Then I used this command. > lo <-glm(hey.count~as.factor(jeo)+as.factor(eg)+as.factor(kon)+ as.factor(yol)+ as.factor(aks)+as.factor(fay),family=poisson,data=dt2) as you see I used c...

...king at mean values of a numeric dep_var (environ.therm) across values of a factor (partyid3). I use ddply from plyr and wtd.mean from Hmisc. The nes requires a weight var (wt).

The following code works: attach(nes) obj1 = ddply(nes, .(partyid3), summarise, var = wtd.mean(environ.therm, wt)) print(obj1) plotMeans(obj1$var, obj1$partyid3, error.bars="none") Here is what happens when I write and run the function, meanN: meanN=function(data,x,y,w=NULL) + {obj1=ddply(data,.(x),summarise, var=wtd.mean(y,w)) + print(obj1) + plotMeans(obj1$...
