similar to: Looping through names of both dataframes and column-names

I've been stuck with this problem for a whole afternoon. It's silly but totally pissed me off. I have a set of data frames with names in a sequence: df_1, df_2, df_3, ..., df_20. Now I want to access each data frame (read or write) in a for loop, in a way something like this: for (i in 1:20) { df_i <- ###### length(which(df_i[,7]==1)) ###### } I tried paste or cat

Buen día estimados, Tengo el siguiente código: df_1 <- data.frame(ana = c(15, 20, 30), maria = c(15,20,30), jose = c(15, 20, 30)) df_2 <- data.frame(nombre = c("jose", "ana", "maria"), valor = c(1,2,3)) # Find the corresponding columns in df_1 based on the values in df_2$nombre cols <- match(df_2$nombre, names(df_1)) # Subtract the values of df_2$valor

Dear All, I would be grateful if you can tell how can I suppress the legend (automatically created) when I plot a groupedData. suppose that I have data farme df_0 which contains the following columns: ID represents the clusters, t represents time of observation, Y: the variable of interest and X a binary covariate. Then: df_1 <- groupedData(Y ~ t | ID) plot(df_1,

This all stems from the ancient bad decision by Microsoft to translate LF characters to CR LF when writing text files. R passes 0A or 0A 00 or 0A 00 00 00 to the output routine (part of the C run-time), and it needs to figure out how many

Thanks for looking into this. A few notes regarding all the UTF encodings on Windows 10 ... The default eol for write.csv (via write.table) is "\n" and always gives as.raw (c (0x0d, 0x0a)), that is, <Carriage Return> <Line Feed> as adjacent bytes. This is fine for UTF-8 but wrong for UTF-16 and UTF-32. EXAMPLE: Using UTF-32 for exaggeration (note also that 3 nul bytes are

Package: src:xen Version: 4.17.0+46-gaaf74a532c-1 Severity: important Two major bugs have shown with the release of new hardware from AMD. Since the new hardware is likely to become common during the life of Debian/bookworm, you may wish to grab them early: ad15a0a8ca2515d8ac58edfc0bc1d3719219cb77 x86/time: prevent overflow with high frequency TSCs Turns out the latest generation is fast enough

Initially out there as #965245. I strongly prefer to build ARM64 packages on non-ARM systems. Something about my main build machine having twice the cores and twice the clock speed. As such after many builds I've managed to generate a set of patches which appear to mostly function to get functioning cross-builds of Xen. These are NOT a 100% solution. Some packaging hacks were needed. In

I haven't yet done as much experimentation as Andreas Pflug has, but I can confirm I'm also running into this bug with Xen 4.4.1. I've only tried Linux kernel 3.16.43, but as Dom0: EDAC MC: Ver: 3.0.0 AMD64 EDAC driver v3.4.0 EDAC amd64: DRAM ECC enabled. EDAC amd64: NB MCE bank disabled, set MSR 0x0000017b[4] on node 0 to enable. EDAC amd64: ECC disabled in the BIOS or no ECC

Fewer fork()s and execve()s quickly add up to significant savings. I'm concerned Debian is slowly headed towards recreating SunOS^WSolaris 5.7^W2.7^W7 and the layers and layers of scripts which killed performance. As these runtime scripts are heavily used, avoid all uses of external programs by them. Signed-off-by: Elliott Mitchell <ehem+debian at m5p.com> --- The gains from this

I need to read csv files repeatedly, named data1.csv, data2.csv,? data24.csv, 24 altogether. That is, data<-read.csv(?data1.csv?) ? data<-read.csv(?data24.csv?) ? Is there a way to do this in a loop? Thank you. Steven from iPhone [[alternative HTML version deleted]]

Dear R Helpers, I have run into a problem trying to perform a number of actions on a set of quantmod data objects through a loop and I am hoping that this is an easy problem for someone else as opposed to very difficult for me. The example task is to get the first three objects of the quarterly balance sheet for a number of companies from the getFinancials object and put them together into a

Hi all, I have a couple of questions. 1) Is there a more effective way to remove the following pattern (patternrm) from the station_id_Timeseries (see below) patternrm <- c(_2000_4_OND, _2001_1_JFM, _2001_2_AMJ, _2001_3_JAS, _2001_4_OND, _2002_1_JFM, _2002_2_AMJ, _2002_3_JAS, _2002_4_OND, _2003_1_JFM, _2003_2_AMJ, _2003_3_JAS, _2003_4_OND, _2004_1_JFM, _2004_2_AMJ, _2004_3_JAS, _2000_4_OND) #

Hi Team , I have a requirement of building set of panels in which each panel has multiple visuals based on single set of dataset values and this thing is repeated for other set of values as well. For this requirement , I am trying to use a for loop to create visuals and panel for each set of values ( like first panel should be for first set of dataset values and so on) . Do we have any available

Hi, I'm Wellington from Brazil and I have the following issue: I've been working on a project a for a while, and I'm having trouble in using the loop (for) I need to read a column (c1), and for each value of this column, I need to check if it's within the control limits So, I was trying to do this: For (k in 1: c1) If (c1< lcl1 | c1 > ucl1) {here I

Hey All, So, I am confused how exactly to use nesting loop functions in R to spit out data frames. I've managed to create a working function for my data set that generates a data frame for a given set of Year i and Location j; but how would I do it for all Years and Locations? Here is my working function: test<-function(i,j){ a<-x[which(x$Year==i & x$Location==j),]
