Re: [R] Complicated analysis for huge databases

Thanks Boris , this was very helpful but I'm struggling with the last part. 1) I combined the first 2 columns :- library(tidyr) SingleMealsCode <-unite(MyData, MealsCombinations, c(MealA, MealB), remove=FALSE) SingleMealsCode <- SingleMealsCode[,-2] 2) I separated this dataframe into

Rolf, looking at the configure script I believe you need to specify --with-tcl-config=/usr/lib/tcl8.6/tclConfig.sh and similarly --with-tk-config= HTH, Peter On Fri, Nov 17, 2017 at 8:43 PM, Rolf Turner wrote: > On 18/11/17 17:00, Erin Hodgess wrote: >> >> When I

Re: [R] family

This question is about algorithm help... or rather, "do my work for me", not about R. Study up on "directed acyclic graphs" [1]... there actually are some packages related to such data structures on CRAN (e.g. pooh::tsort, Task View gR "gRaphical Models in R"), but you should at least be aware

Something like the following? AllMAFs <- list() for (i in length(SeparatedGroupsofmealsCombs) { AllMAFs[[i]] <- apply(SeparatedGroupsofmealsCombs[[i]], 2, function(x)maf(tabulate(x+1))) } (untested, of course) Also the solution is a bit generic since I don't know what the output of maf()

[R] tcltk problems

It recently came to my attention that my R installation no longer has tcltk capability. I can't figure out why or what to do about it. I built R from source. I configured using the "--with-tcltk" flag. The build and install *seemed* to go OK, but after realising I didn't have tcltk

[R] family

Hi all, I am reading a huge data set(12M rows) that contains family information, Offspring, Parent1 and Parent2 Parent1 and parent2 should be in the first column as an offspring before their offspring information. Their parent information (parent1 and parent2) should be set to zero, if unknown.

Re: [R] Complicated analysis for huge databases

Combine columns 1 and 2 into a column with a single ID like "33.55", "44.66" and use split() on these IDs to break up your dataset. Iterate over the list of data frames split() returns. B. > On Nov 17, 2017, at 12:59 PM, Allaisone 1 wrote: > > > Hi all .., > > >

Re: [R] Converting a string to variable names

Do you mean that you have One data frame, and it has a bunch of variables within it named P1, P2, P3... or A bunch of data frames names P1, P2, P3... ? I'll assume it's the latter. Here is one way: dfnms < c('P1', 'P2', 'P3') for (nm in dfnms) { tmp <- get(nm) rownames(tmp) <-

Re: [R] RStudio blank upon opening

You should ask this in the RStudio support forums.. it is not about R. I will say anecdotally regarding such behavior that RStudio expects certain directories that it creates to be hidden (e.g. the .Rproj.user directory for projects) so if you copied or otherwise messed with those files then

As Jeff recommends, I use the pkg::fun for clarity. However I probably use it more than needed (e.g. I use the dplyr:: prefix on all dplyr function calls instead of just the functions with name collisions). Are there any tools that can be used (like a form of lint) to identify uses of functions
