How to create a random vector for a range of values in R?
To create a random vector for a range of values, we can use sample function. We just need to pass the range and the sample size inside the sample function. For example, if we want to create a random sample of size 20 for a range of values between 1 to 100 then we can use the command sample(1:100,20) and if the sample size is larger than 100 then we can add replace=TRUE as shown in the below examples.
Example
x1<-sample(101:255,20) x1
Output
[1] 242 213 223 132 138 232 251 229 151 170 136 206 153 152 116 173 162 169 181 [20] 225
Example
x2<-sample(101:255,200,replace=TRUE) x2
Output
[1] 243 124 176 166 220 196 171 189 132 174 213 118 102 153 208 108 183 191 [19] 150 143 113 175 172 115 180 101 176 101 195 137 167 252 208 145 115 255 [37] 144 147 187 212 158 227 112 254 196 195 169 239 233 198 210 106 107 219 [55] 198 249 220 216 136 156 146 235 160 243 219 102 157 241 131 151 236 243 [73] 180 141 103 201 135 154 192 108 133 214 118 119 112 160 117 141 107 103 [91] 122 137 217 181 246 187 192 202 143 119 217 153 220 150 214 246 189 128 [109] 192 220 217 239 215 220 201 223 240 246 177 246 231 117 115 252 118 144 [127] 234 235 225 156 157 228 154 186 116 250 158 180 238 244 208 191 168 254 [145] 214 207 193 118 221 193 157 192 178 190 235 245 241 128 111 118 108 232 [163] 223 234 218 158 169 108 152 233 181 209 145 186 138 140 215 164 206 142 [181] 118 139 115 220 171 158 242 183 149 137 141 175 102 145 247 189 124 111 [199] 254 123
