Would it be any better to teach free_tree() to be more free()-like by being a no-op on NULL? -- Eric Blake, Principal Software

Hello Folks, I have 5 columns for thousands of tree records that record whether that tree was alive or dead. I want to recode the columns such that the cell reads "found" when a live tree is first observed, "alive" for when a tree is found alive and is not just found, and "mort" when it was previously alive but is now dead. Given the following: > tree_live

The majority of the tools have already options (--echo-keys & --keys-from-stdin) to deal with LUKS credentials, although there is no way to automatically provide credentials. --keys-from-stdin is suboptimal, because it is an usable solution only when there is just one device to open, and no other input passed via stdin to the tool (like the commands for guestfish). To overcome this

Hello, The following code does'nt work for me. The last command reports an error. I have created a consensus tree using the consensus comand from phylo but cannot manipulate the phylo object afterwards to create a dendogram , by transforming the phylo object into a hclust object and then into a dendogram ?? Thanks for any help library(ade4) library(cluster) library(stats) library(ape)

Hi All, There is something I don't quite understand about R memory management. I have the following function function (AdGroupId) { print(memory.size()) channel <- odbcConnect("RDsn", uid = "xxxx", case = "tolower", pwd = "xxxxxx") Tree1 <- sqlQuery(channel, "exec SelectAdgroups 111120,0", as.is = c(FALSE, FALSE,

From: Nikolay Ivanets <stenavin@gmail.com> This patch adds '--blocksize' command line option parsing and handling for guestfish and other C-based tools which share the same code from this sub-module. '--blocksize' will be a common for almost all libguestfs-based tools and thus parameter description will be repeated all the time. Let's move it into blocksize-option.pod

The device name is only used by guestfish (when using the -N option to prepare drives). We constructed the device name very naively, basically ‘sprintf ("/dev/sd%c", next_drive)’. This stores the device index instead, and only constructs the device name in guestfish. Also the device name is constructed properly using guestfs_int_drive_name so it can cope with #drives > 26. ---

Hi all, I am a phylogenetic student, I'm running SH test to examine free (tree1) and constrained (tree2) trees using R phangorn package. The outputs are like the following and i'm confused how should i interpret them!!!   Trees      ln L           Diff ln L    p-value [1,]     1 -1422.921   0.00000  0.4952 [2,]     2 -1457.282  34.36085  0.0201 Why it gives us two p values? Would you

Hello, R-users,   I have a datafile with 37313 records and each record has 5 different measurements on the same variables. The format looks like this: treeID, VIG0, VIG1, VIG2, VIG3, VIG4 I was trying to convert the one row record to 5 rows record with format like this (treeID, MEASUREMENT, VIGOR). My code like this:   treeMeas<-matrix(data=0,nrow=(length(tree1$indivTree)*5), ncol=3)

Dear R-help subscribers, I have a quite stupid question about using lapply.

Hello R-users, I apologize for my question but I'm a newbie. I want to read a file which columns separator is "\t". At the end of each row there is a "\n" to go to the following line. The three first lines are remarks lines and the fourth contains columns titles ( variables names, ids, dates, calculated values, observed values...) . I do: read.table("myFile",

Hi, I am somewhat new to R so this question may be foolish, but is it possible to add decision trees into a list, array or vector in R? I am trying to build a collection (ensemble) of decision trees. Every time a new instance arrive I need to get the prediction of each decision tree. I have tried to add a decision tree into a variable but without luck. Is a special package needed perhaps? This

I have two identical disks /dev/sdb1 == source /dev/sdc1 == dest When I rsync the source -> dest rsync -a /tree2/ /tree2m the destination size id considerably larger. /dev/sdb1 17654736 6513064 10244848 39% /tree2 /dev/sdc1 17654736 7691192 9066720 46% /tree2m When I look down into the directories I find the following /tree2 ...

So I have 2 sets of data - a training data set and a test data set. I've been doing the analysis on the training data set and then using predict and feeding the test data through that. There are 114 rows in the training data and 117 in the test data and 1024 columns in both. It's actually the same set of data split into two. The rows are made of 5 different numbers. They do represent
