similar to: For each entry type in column?

It?s sometimes faster to ask from someone who has already learnt the syntax. In this case one has to do e.g. names(data$somecol) To get the collection and then iteration through it is almost like in Python: for(i in names(data$somecol)) { # do something } > Bert Gunter <bgunter.4567 at gmail.com> kirjoitti 6.11.2017 kello 19.55: > > Time to go through a tutorial or two! --

Matti - Since you are asking about looping through a column, not looping across columns, it is simply the following: # Note: data.frame() turns strings into factors by default. myDF <- data.frame(type = c("a", "j", "a", "a", "j"), weight = c(12.3, 6.8, 10.5, NA, "5.5")) myDF$type # ... is a vector of factors

Hello, If you want to loop through the columns of a data.frame you can do for(i in names(df)){ [code] } Another way would be lapply(names(df), function(somecol) class(df[[somecol]])) where class(df[[somecol]]) is just an example, you would use whatever fits your needs. When you say that the column in question holds "levels" do you mean it's a factor? (factors are R's

Your query evidences some basic confusion, but ?tapply or the equivalent lapply(split(...)) construct are most likely relevant.

Boris: "As others have remarked, for added efficiency with large datasets we often use functions from the apply() family, rather than for-loops." That is generally false, though it is a common misconception. Apply-type functions are used to maintain fidelity -- and for some, clarity -- to a functional programming paradigm.

Hi, It seems that setting a with_scope on the parent class doesn''t do anything MyClass.with_scope(:find=>{:conditions=> ["somecol = ?", ''val'']}) do @ext_pages, @ext_rows = paginate :my_extended_class, { :per_page => 13 } end # this doesn''t generate WHERE somecol=''val'' In order for scope to work you have to call

This patch set a gap (4 bytes) between xattr entry and name/value when xattr in bucket. This gap use to seperate entry and name/value when a bucket is full. It had already been set when xattr in inode/block.

So. I've builded 4.19.2 from source. building worked fine and I've configured like the following: ./configure \ ?? ?--sbindir=/usr/local/sbin \ ?? ?--bindir=/usr/local/bin \ ?? ?--sysconfdir=/etc/samba \ ?? ?--mandir=/usr/share/man \ ?? ?--systemd-install-services \ ?? ?--with-systemddir=/lib/systemd/system \ ?? ?--enable-selftest \ ?? ?--disable-cups I ran make quicktest with

After reading a data.frame using, such as a <- read.spss("data.sav") I want to give the column index 'i', or a[i] to a function, which after some calculation, should print out the results to the standard output. I am struggling how to access the data itself, as e.g. sum(a[i]) does not work in this context. In addition I need to know the name of the variable within the

Hello I recently switched from Nvidia binary driver to Nouveau. I have encountered a possible bug in the kernel module. Before I file a bug report I would like to know if this is a known issue or not. I believe it is related to sleep state and power management of the driver. The Bug: When the computer is left on it's own to go to a power save mode X takes 100% CPU-time in its thread. A

I came across a race condition in lightdm greeter setup phase before the login screen is displayed (at boot time or after logout). I reported this also on Launchpad with more details (https://bugs.launchpad.net/lightdm/+bug/1172752), but to work on a proper fix, ideas on how to fix this would be welcome. During greeter setup "lightdm --session-child" is spawned twice. The first call to

Hello, Here is a dilemma I am having for a long time. But, I couldn't figure it out. I have an vector of Y and a data frame named "data",which contains all Xs. I tried to be more efficient in fitting a simple linear regression with each X. Firstly, for (i in 1:(dim(data)[2])){ model<-lm(Y~data[,i]) # this is not what I want since the name of coefficient will be data[,i] # I

Hi, Could CentOS kernel keepers apply following patch on current kernel? http://patchwork.ozlabs.org/patch/95785/ (Current as: 2.6.32-71.29.1.el6.x86_64) With the patch applied, and a ".local" kernel built, I get 30% higher throughput with vmxnet3 in my IP routing node, than when using e1000 "card" at the same. Without the patch, the TCP flow over vmxnet3 driver on a

Some HSM's such as Safenet Network HSM do not allow searching for keys unauthenticated. To support such devices provide a mechanism for users to provide a pin code that is always used to automatically log in to the HSM when using PKCS11. The pin code is read from a file specified by the environment variable SSH_PKCS11_PINFILE if it is set. Tested against Safenet Network HSM. ---

Hi!Is it possible to get the samba authenticate a user and map to his homedirectory only using posixaccount or are there some attributes that windows absolutely require like in the samba-objectclasses?Any configuration examples if this is possible.I have been experimenting with pam.d/samba using pam_ldap.so module, but no success so far.Currently I have setup the server so it can authenticate a
