I've got two data.frames and, when certain "keys" match, I would like to add the column values from one data frame to the other data.frame. Below I list the two data.frames, i.e. neighborhoodInfo_df, and schoolZone_df. Based on the "address" key I would like to add the "schoolZone" key to the neighborhoodInfo_df data.frame. By any chance is there an R

Andreas, As far as I can tell (/conjecture), this is because the list of classes a particular class inherits from directly is appended to as needed, and so the order that a class extends others isd refined by the order that those connections are defined. We can see this with two setClassUnion calls, rather than required setAs: > setClass("grandma", slots = c(a =

Dear colleagues, there is a behaviour with S4 (virtual) classes that I find very hard to understand: Depending on the position of setAs(), the tree of inheritance changes. This is my baseline example that defines the classes "grandma", "mother", "daughter" and a virtual class "mr_x". For a new instance if "daughter", "mr_x" is betweeen

Dear R users, I have a matrix with 2 columns with the variables: "daughter index", "mother index". I would like to draw a network digraph using this data, where each daughter is connected to a mother and between the connections inlcude a circle with the information on the indices ("daughter index", "mother index"): i.e. something similar to graphs

Take this as an example: > a=data.frame(col1=c(1,2,3,4,5), col2=c ("my","beloved","daughter","son","wife")) > b=data.frame(col1=c(1,2,4), col2=c("my","beloved","son")) > a col1 col2 1 1 my 2 2 beloved 3 3 daughter 4 4 son 5 5 wife > b col1 col2 1 1 my 2

Please chime in if you've ever wished for digium to make a 4-port daughter board with a combination of 2FXO AND 2FXS ports on the same card. When using the 800 series cards, one must either choose 4-port permutations of FXS/FXO, OR one must give up 2 valuable ports. In other words, when you add ONE 100-series daughter board, you give up TWO of your physical ports. Is there a technical

Dear List, I?m trying to figure out *memory page sharing***using HVM on Xen 4.0.1, but I?m not really able to find some useful information or sources about this issue. I just found two links porviding these sources: http://knol.google.com/k/learning-grant-tables http://blog.chinaunix.net/space.php?uid=20286427&do=blog&id=109114 Both are not working..

I have an embedded linux board (main board), which has multiple Ethernet interfaces, and a daughter card, which has one Ethernet interface. The diagram is shown as following. +---------+ +----------------------------+ | daughter |--------------------| ptp |---------------- | card | Ethernet |

Hi all! The randomForest in R enables us to prune the trees using the nodesize feature where we can stop splitting a node if it contains less than the specified no.of of records/entities at that node. However is there a way to stop the tree growing after a specified number of levels. To be more clear on what I mean by a level. Level 0 is the parent node, Level 1 has 2 daughter nodes, Level 2 has

I''m trying to build out a test cloud using XCP 1.0.0 beta with 3 machines of 18 cores total (Phenom II 1090s). I''ve built three machines, installed XCP 1.0.0 beta on them and they all three have the same problem - the Realtek network cards don''t work. The following is the output from lspci 03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI

My wife and daughter, and to lesser extent myself and my daughters boyfriend would like a communications system which allowed us to talk to each other, both on a one on one basis, but also occassionally in conference. My wife and I live in a house with an internal LAN with each of us with a desktop machine (hers in Windows XP, mine runs Linux) and a Linux server acting as firewall and NAT

Hello!

Howdy, R Grues I have enjoyed R, but I cannot solve one problem easily. Please help my problem. When I tried the R script, I got the following Error. This error results from input data file exported through a Excel spreadsheet software. Error in step(lm(pop.rate ~ as.numeric(year) + as.factor(policy) + as.numeric(nation.grant) + ?: ??number of rows in use has changed: remove missing values?

My daughter likes to play games on noggin.com and nickjr.com. The problem is that some of them will play with Flash 9, which I have installed, but many require Shockwave, which doesn't exist for Linux. Is there any way to get a shockwave plugin to work with Firefox 2.0 and a 2.6.x kernel. My daughter would really appreciate it, and so would I! Marc Shapiro

Hi there, I'm trying to repurpose an unused machine (athlon XP 3000+) for my young daughter to use. It's on a motherboard with a VIA KT880 chipset and VIA integrated soundcard (VIA 8237). The card seems to be detected during boot time and shows up in the system log, but when I try to actually use the sound card within Gnome, there's no sound. The device is detected, but

I'm working with the randomForest package and have successfully build a model. I'd like to go one step further however, and use the output from the model to construct a map using the output. My input data are spatial, and I have an independent set of rasterize maps for each of the predictor variables, to map the classification solution. Using the getTree function: >

Hi all. I have had this apparently inconsistent behavior in smbclinet since, around 4.11.(6?). 4.11.0 seems fine. I am on fedora 31 so I have just been keeping smbclient at 4.11.0 but that is not an option in stock fedora 32 which I would like to use now. My main problem with it is that it seems to be stopping automount working on samba shares of Fed32 clients. Any suggestions welcome... This

Hello. We're setting up fts solr and want to have the solr server host be set per-user via UserDB. It looks like if a user connects and fts indexes mail, and then another user connects and indexes mail, indexer-worker is connecting to the first user's fts host: User1, hammer at rp-auth-test.com connects, does a SEARCH for the first time, indexer-worker gets UserDB settings and

Hi all, I have a surplus Sangoma 10 port FXO card for sale. This model could be upgraded to 12 ports or even changed to FXS or a combo of FXO/FXS by changing the grand-daughter cards (each card supports 2 lines). You could also "downgrade" the card by removing any or all of the daughter cards. I'm asking US$450 plus shipping to the lower 48. Paypal or Master/Visa only. Thanks
