[R] rbind with partially overlapping column names

Hello, I would like to merge two data frames with partially overlapping column names with an rbind-like operation. For the follow data frames, df1 - data.frame(a=c(A,A),b=c(B,B)) df2 - data.frame(b=c(b,b),c=c(c,c)) I would like the output frame to be (with NAs where the frames don't overlap)

[R] glm with within-subject factors

Hello, I am analyzing a dataset where the response is count data. I have one two-level factor that is repeated within-subjects and additional between-subject variables that are either categorical or continuous. I have previously modeled a comparable dataset (without the within-subjects factor)

[R] get list element names within lapply / sapply call

Hi all, I would like to iterate through a list with named elements and access the names within an lapply / sapply call. One way to do this is iterate through the names and index the list with the name. Is there a way to iterate through the list elements themselves and access the element names

[R] d.f. in F test of nested glm models

Dear all, I am fitting a glm to count data using poison errors with the log link. My goal is to test for the significance of model terms by calling the anova function on two nested models following the recommendation in Michael Crawley's guide to Statistical Computing. Without going into too

Re: [R] Scatterplot_row match

Hi, What if you create two data frames, then merge them by gene id. If your data is in a data frame called dframe... df1 - subset(dframe,select=c(id2c,2c)) df2 - subset(dframe,select=c(id1c,1c)) merged - merge(df1,df2,by.x=id2c,by.y=id1c,all=TRUE) plot(merged$1c,merged$2c) Cheers, Jonathan
