Question

我的数据就是这样-

with open('README.md', 'r', encoding='utf-8') as fh:
    TypeError: 'encoding' is an invalid keyword argument for this function

我要这样排列-

p1  x1
p2  x2
p1  x3
p7  x4
p5  x5
p2  x6
p5  x7
p7  x8
p1  x9
p2  x10

我该如何使用R /命令行或Excel？

Answer 1

我们可以使用aggregate

aggregate(col2 ~ col1, df1, toString)

如果元素重复，则获取unique行并进行aggregate

aggregate(col2 ~ col1, unique(df1), toString)

Answer 2

您可以使用dpylr按组group_by paste，然后按组library(dplyr) group_by(df, c1) %>% summarise(c2 = paste(c2, collapse = ",")) #### OUTPUT #### # A tibble: 4 x 2 c1 c2 <fct> <chr> 1 p1 x1,x3,x9 2 p2 x2,x6,x10 3 p5 x5,x7 4 p7 x4,x8第二列：

const that = this;
const valueline = d3.line()
  .x(function (d, i) {
    return that.x(d.date) + 0.5 * that.x.bandwidth();
  })
  .y(function (d) {
    return that.y(d.value);
  });

this.x.domain(data.map((d: any) => d.date));

this.y.domain(d3.extent(data, function (d) {
  return d.value
}));

const thisLine = this.chart.append("path")
  .data([data])
  .attr("class", "line")
  .attr("d", valueline);

const totalLength = thisLine.node().getTotalLength();

thisLine.attr("stroke-dasharray", totalLength + " " + totalLength)
  .attr("stroke-dashoffset", totalLength);

thisLine.transition()
  .duration(1500)
  .attr("stroke-dashoffset", 0)

let circle = this.chart.selectAll("line-circle")
  .data(data);

circle = circle  
  .enter()
    .append("circle")
    .attr("class", "line-circle")
    .attr("r", 4)
    .attr("cx", function (d) {
      return that.x(d.date) + 0.5 * that.x.bandwidth();
    })
    .attr("cy", function (d) {
      return that.y(d.value);
    })  

circle  
  .attr("r", 4)
  .attr("cx", function (d) {
    return that.x(d.date) + 0.5 * that.x.bandwidth();
  })
  .attr("cy", function (d) {
    return that.y(d.value);
  })   

circle
  .exit()
  .remove()

如何在一行中排列属于一组的元素
