assign

问题 I am trying to assign a plot to a list that is named via variable ( snm ). My code snippet is all the variations that I tried to do to make it work. What other option am I missing? Thanks. My goal is to loop over my graph assignments, using an IF statement to change the snm and a few other variables that I will use in the graphs. for (x in seq(0,1)) { if (x==0) { snm="grad" } else if (x==1) { snm="start" } assign(snm,list(),envir=.GlobalEnv) #works assign(snm[[1]],ggplot(data=TDSF, aes(x

问题 If a user click on a button which has class name: '3-col', it will execute the following code: '{% assign products_per_row = "3" %}'. and if a user click on a '4-col' button, it will execute the following code: '{% assign products_per_row = "4" %}'. However the code below doesn't work. I have researched all ways to do that, but I couldn't. Any advice is appreciated. Thanks! <button class='3-col' onclick="prod3()"></button> <button class='4-col'onclick="prod4()" ></button> {% include 'product

问题 I'm looking for a script in Phyton or Mel where is can assign different materials to an OBJ imported file from Rhino and the same materials to the next OBJ file also imported from Rhino. Is that possible? Here's what I have tried: import maya.cmds as cmds import glob def importFile(i): cmds.file(i, i=True, groupReference=True, groupName="myobj") def materialFile(): cmds.select("myobj") myMaterial = "blinn2" cmds.sets( e=True, forceElement= myMaterial + 'SG' ) The obj files parts come in

问题 Here's my fiddle https://jsfiddle.net/tuc1faug/1/ Here I have assigned the colors with the specific values using jquery. Colors will be shuffled each time.Now i want these values to be hidden in the cells and I want all those values to be stored into an array in that shuffled order Html: <table border="5px" width="500px" height="50px" align="center"> <tr id="colors"> <td height="50px" orderId="1" bgcolor="red"></td> <td height="50px" orderId="6" bgcolor="brown"></td> <td height="50px" orderId

问题 I've got a list of tones which I've made, I've managed to get them into a list but now I'm faced with the challenge of allowing the user to "touch and hold" to assign as a notification tone. Here's the code from MainActivity.java: import java.util.ArrayList; import android.app.ListActivity; import android.media.MediaPlayer; import android.os.Bundle; import android.view.ContextMenu; import android.view.ContextMenu.ContextMenuInfo; import android.view.MenuInflater; import android.view.View;

问题 In testing, it would be convenient to have a simple singleton data model that acts like an array. That is, if I have a singleton class called MySingletonClass that supports a sharedInstance variable you should be able to change an element in the array with subscripts: MySingletonClass.sharedInstance[ 0 ] = "New item 0" Also, when the app opens, it would be great if a simple assignment allowed the system to provide initial values to the array: MySingletonClass.sharedInstance = ["Item 0", "Item

问题 This question is an extension of the excellent answer provided by Robert Picard here: How to Randomly Assign to Groups of Different Sizes We have this dataset, which is the same as in the previous question, but adds the year variable: sysuse census, clear keep state region pop order state pop region decode region, gen(reg) replace reg="NCntrl" if reg=="N Cntrl" drop region gen year=20 replace year=30 if _n>15 replace year=40 if _n>35 If I just wanted to re-randomly assign reg 's across all

问题 Say I have a dataset and I want to assign observations to different groups, the size of groups determined by the data. For example, suppose that this is the data: sysuse census, clear keep state region pop order state pop region decode region, gen(reg) replace reg="NCntrl" if reg=="N Cntrl" drop region *Create global with regions global region NE NCntrl South West *Count the number in each region bys reg (pop): gen reg_N=_N tab reg There are four reg groups, all of different sizes. Now, I

问题 I have a function that Finds the Critical Points of a function. function [ cr ] = CritPt(f, var1, var2) f = sym(f); fx = diff(f,var1); fy = diff(f,var2); [xcr,ycr] = solve(fx,fy); crpt = [xcr,ycr] I am supposed to use the function CritPt in the Command Window to define a variable called cp which contains the critical points of f(x,y)=x^2*y+(1-y)^2 When I attempt this I get: >> cp=CritPt('x^2*y+(1-y)^2','x','y') crpt = [ 0, 1] [ 2^(1/2), 0] [ -2^(1/2), 0] Error in CritPt (line 2) f = sym(f);

问题 I am trying to assign a column of data to a new column in an existing data frame. The data frame changes in a loop, from scores.d, to scores.e. My desired output is to have scores.X$new.col populated with the vals, where X is replaced with the current dfname. dfnames <- c("d","e") scores.d <- data.frame(x = 1, y = 1:10) scores.e <- data.frame(x = 2, y = 10:20) vals <- 60:70 for (i in seq_along(dfnames)){ assign(get(paste0("scores.",dfnames[i]))$new.col,vals) } Error in assign(get(paste0(
