यहाँ एक तरीका है। मैंने नीचे data.table
पैकेज का उपयोग किया है, इसलिए यदि आपके पास यह नहीं है, तो कृपया इसे पहले इंस्टॉल करें। यदि आप वास्तव में पसंद करते हैं कि प्लॉट नियमित डेटा फ्रेम का उपयोग करके बनाया जाए, तो मुझे बताएं और मैं तदनुसार इसे समायोजित कर दूंगा।
library(data.table) # Install via install.packages(data.table)
# x is the vector of numbers for which you want to create the stem and leaf plot
# leftDigits gives the position of the '|' relative to the decimal point,
# e.g. leftDigits = 0 will result in 43.2 being represented as 43 | 0.2
# e.g. leftDigits = 1 will result in 43.2 being represented as 4 | 3.2
# I have included a rounding parameter, due to floating point problems seen when taking the difference of two numbers
# rounding = 2 means that your numbers will show to 2 decimal places. Change as desired.
myStem <- function(x, leftDigits, rounding = 2){
data = data.table("x" = x) # Create a data.table
data[, left := floor(x/10^leftDigits)] # Get the number that will be to the left of '|'
data[, right := round(x - left*10^leftDigits, rounding)] # The remainder will be on the right
data = data[, paste(sort(right), collapse = ", "), by = left] # For each 'left', Place all the 'right' values in a comma separated string.
data[, out := paste(left, " | ", V1), by = left] # Add the "|"
cat(data$out, sep = "\n") # Output
}
# Example
myStem(x = c(43.2, 45.3, 48.1, 54.2), 1)
# 4 | 3.2, 5.3, 8.1
# 5 | 4.2
संपादित: आप भूखंड वापस करने के लिए एक वापस चाहते हैं, तो उसके बाद निम्न कोड काम करना चाहिए। यह पिछले कोड के रूप में एक समान तरीके से काम करता है

धन्यवाद, मैं इसे की कोशिश करेंगे। –
मुझे अभी एहसास हुआ कि मैं इच्छित प्रारूप नहीं देता हूं। @rawr आपको चाहता है कि आप चाहते हैं। कृपया उसका जवाब देखें। – jav
आपका उत्तर महान है, साथ ही साथ उसका भी। –
