search for: reordering

It was recently pointed out on the lists that the S-PLUS Trellis suite has a function called reorder.factor that's useful in getting useful ordering of factors for graphs. I happily went ahead and implemented it, but it turns out that R (not S-PLUS) has a generic called reorder (with a method for "dendrogram"). Naturally, this causes R to think I'm defining a method for

I am trying to use an integer object as a flag item for displaying a link on a page called reorder that is a column in my PlanProcedures table. I''m getting an error that says The Header is NoMethodError in Manage_plan_procedures#list missing attribute: reorder Here is what my model looks like: >> PlanProcedure.column_names => ["id", "plan_id",

reorder() is probably the best way to order the levels in a vector without manually specifying the order. But reorder() orders by default in an increasing order: "The levels are ordered such that the values returned by ?FUN? are in increasing order." Is there a way to do what reorder() does, but order the levels according to a _decreasing_ order of the values? Sverre

Hello all ,  I have a data frame like this  X1X2X3 11815 22916 331017 441118 551219 661320 771421 now i want to randomly reorder the variable X2  but the row element should be same  as for example  X1X2X3 12916 251219 331017 471421 561320 61815 741118 how can i do that ?? Hint :  this could be helpful :  if X2 is only a vector like this  X2<-c(8,9,10,11,12,13,14) so i can easily reorder

...t information. The preliminary documentation for heatmap.2 is inconsistent in at least a couple of places when discussing the suppression of one or more dendrograms (and column/row ordering in general). In the Details section, in regards to the Rowv and Colv parameters, "If either is NULL, no reordering will be done for the corresponding side." The default value for these parameters is NULL. With NULL, the dendrograms are computed (and hence reordering is done). In the Arguments section, Rowv shows "determines if and how the row dendrogram should be reordered. Either a dendrogram or a...

Or at least is seems that way to me. It's not a big problem, but the behavior doesn't match the documentation. (I think r-help is the place to report this. ) > x <- factor(1:5) > x.ro <- reorder(x, rnorm(5)) > is.ordered(x.ro) # should be FALSE according to ?reorder [1] TRUE > > x.ro <- reorder(x, rnorm(5), ordered=FALSE) > is.ordered(x.ro) # should be FALSE

...trinsics, i.e.__dsb and __isb that require the compiler not to reorder instructions around their corresponding built-in intrinsics(__builtin_arm_dsb, __builtin_arm_isb), including non-memory-access instructions.[1] This is currently not possible. It is sometimes useful to prevent the compiler from reordering memory-access instructions as well. The only way to do that in both GCC and LLVM is using a in-line assembly hack: asm volatile("" ::: "memory") I propose adding two compiler scheduling barriers intrinsics to LLVM: __schedule_barrier_memory and __schedule_barrier_full.

Hi,Can I use "reorder" function with barchart as in dotchart? Here are some codes which do not work for me. Thanks Chetty ___________________________ a1c.cast$bmi.cat.reordered[a1c.cast$eth!="Other"] <-with(a1c.cast[a1c.cast$eth!="Other",],reorder(bmi.cat.ordered[a1c.cast$eth!="Other"], BP.FN.RATE,median )) barchart(BP.FN.RATE~

Hello all, thanks for your time and help. Below are my commands, and it generates a really nice plot, however I am not happy with the reorder() function. I would like the order to be the same as they appear in the genotype variable "genotype <- c("CJ1450 NW 4/25/12","CJ1450 BAL 4/25/12","CJ1450 NW 4/27/12","CJ1450 BAL 4/27/12","CJ1721 NW

Hi, Please help to correct my error in the following. I want to plot the values of 'x" in increasing order. ----------------------------------- library(lattice) Name<-c("A","B","C") x<-c(15,20,10) test<-data.frame(Name,x) dotplot(Name~x,test) dotplot(reorder(Name,x)~x,test) "reorder" has no effect! Thanks. Chetty ------------------------

Hi List I have a dataframe (~1,200,000 rows deep) and I'd like to conditionally reorder groups of rows in this dataframe. I would like to reorder any rows where the Chr.Strand column contains a '-' but reorder within subsets delineated by the Probe.Set.Name column. # toy example #### library(plyr) negStrandGene <- data.frame(Probe.Set.Name =

...load q // This is incorrect if p and q may alias In the MemorySSA representation however, there's no syntactic dependency between load/store, because MemorySSA before transformation would look like this: USE(M0) // corresponding to `v = load q` M1 = DEF(M0) // corresponding to `store 10, p` Reordering these two nodes does not break syntactic dependency, hence additional flow-sensitive analysis is needed to check whether reordering is valid. To my understanding, GVNHoist seems to do that: Memory operations in basic blocks are checked by GVNHoist::hasMemoryUse(). If USE nodes of MemorySSA also h...

I've been building a ranked dot plot for several days now and am sorting the data using the reorder command. What I don't understand is how reorder works when mutiple varibles are plotted by grouping. In the example below I'm using re-order to sort by a variable name Resv_Prop, but I'm plotting up to three different values of Resv_prop (different Year values) for each factor.

I'm not sure what the usual "ping time" is for llvm-dev, but may I ask if there are any updates on this? It appears that the following lines are the root cause of the reordering (https://github.com/llvm/llvm-project/blob/fdcb27105537f77c78c4473d4f7c47146ddbab69/llvm/lib/Transforms/InstCombine/InstructionCombining.cpp#L2175): // Handle gep(bitcast x) and gep(gep x, 0, 0, 0).

I find mention of “hot arc” optimization (-fprofile-arcs) , but I’m unclear if this is the same thing. Does Clang PGO do block reordering? It does reordering, but does not do splitting/partitioning. I take this to mean that PGO does block reordering within the function? I don’t see that the clang drive passes anything to the linker to drive function ordering at the linker level as well. Is there something there that I missed, or ar...

I need the species to be displayed in descending

Hi , I would like to know if there is any way to reorder functions in the object file in order to improve code locality by implementing subsections .text.hot. GCC controls this behavior with '-f(no)-reorder-functions' flag, is there any way to do so in clang? Regards, Priyanka -------------- next part -------------- An HTML attachment was scrubbed... URL:
