[R] how to just download file on disk by the link
Sorry for stupid question but is there any way to just download file (excel file) from the url to the disk with a certain name? Now it seems that I should open it (via read.xls) and then write it by write.xls. But I am pretty sure it should be something much easier?

[R] convert table to a string in matrix
Hello everybody! I need help in collecting the information about Russian elections. There is a table at the web-site http://www.moscow_city.vybory.izbirkom.ru/region/region/moscow_city?action=show&root=774003008&tvd=477400389537&vrn=100100028713299®ion=77&global=true&sub_region=77&prver=0&pronetvd=null&vibid=477400389537&type=242 the problem is how to convert this table to a string in order to add it to the table with 25 columns. ReadHTMLTable doesn't work because I need only bold digits and it takes both normal and bold digits and stick them together. What can be done? Thanks!

[R] how to get url content with "?" (question mark) inside
There is an url "http://www.ozon.ru/context/detail/id/5254326/?type=6#buyalso"; If I try to get the data there (by "readLines" or whatever), R downloads actually the content of this url ""http://www.ozon.ru/context/detail/id/5254326"; that is till the question mark. What should I do to avoid the problem? Thanks!

[R] how to convert careers to social network description
There is a dataframe in R that looks that Person --- Organization --- Year In --- Year Out P1X 20012005 P2X 20022006 What is the most quick way to convert it to the table of the connections between two people with a 'strength' equal the number of years they worked together? In this example the result should be something like: Person 1 --- Person 2 --- Strength P1 P2 4 It seems to me that should be some quick and compact way to do this conversion but I don't know how. Thank you for any hints!

[R] how to combine two data frames via factors (or somehow else)
Hello! The question should be very naive, but I am a beginner and stuck with this unfortunately. There is a dataset of people's affiliation to companies that looks like that (a data frame actually) x y 1 a X 2 b X 3 c X 4 f Z 5 e Z 6 g Z where x is a name of a person and y is a company name. That is, a,b,c work in a company X. f,e,g work in a company Z. and there is another dataset with the affiliation of companies. Like that (much much longer in reality): y1 y2 1 X W 2 Z W that means that both X and Z belongs to the same company W. What is the most compact way (without loops etc) to 'attach' the 'head company' from the second dataset to the first dataset so I can have something like: x y owner 1 a X W ... 4 f Z W I know it should be done somehow with factors, but I don't know how.
